RS Components last week showed off a number of the 3D printers in its line-up, including newly available models from 3D Systems that enable users to print objects comprised of more than one colour. At the same event, Dr Adrian Bowyer, inventor of the RepRap, the first low-cost 3D printer, gave a talk about the implications that 3D printing may hold for manufacturing and society in general.
On show at the event in London was the RepRapPro Ormerod, the most up-to-date version of the RepRap device, along with newly available models from 3D Systems, including the third-generation Cube, and the CubePro Duo and CubeX Trio.
The third-generation Cube (below) supports simultaneous printing of two plastic colours, and can fabricate objects up to 152x152x152mm in volume. It is available from RS for £999.
Meanwhile, the larger CubePro model has a fully enclosed print area for a more controlled environment, and can produce objects of up to 275x265x240mm in size. There are three different versions capable of printing with one, two or three simultaneous plastic colours, priced at £2,359, £2,760 and £3,440, respectively. The one shown below is the CubePro Duo.
Offering similar capabilities is the CubeX model, with the CubeX Trio (below) costing £2,384. All of the 3D Systems models are capable of printing using either PLA or ABS plastic, with the Duo models also able to handle nylon. All are also able to support a layer thickness down to 70 micrometres.
In contrast, the RepRapPro Ormerod (below) is supplied in kit form for £399, and is in fact described by its creator Bowyer as an open-source device – meaning that all of the components that make up the printer can be easily sourced off the shelf (such as the motors) or manufactured using another RepRap.
A range of sample 3D objects was also on display, to demonstrate the wide range of things that can be produced by one of these printers.
These included the robotic digger shown in the picture below, which was comprised of 3D printed parts plus motors and a controller with display.
Also on show from 3D Systems was the Sense 3D scanner that enables users to capture real objects – even people's heads – and then print them out as a model.
At the event, Bowyer spoke of the wider implications of 3D printing as the technology improves and becomes more widely adopted. Overall, he expected that 3D printing would be a good thing, enabling ordinary people to become more creative and to manufacture objects for themselves that would otherwise require a factory to produce.
He was also dismissive of the notion that 3D printers would destroy industry, saying that many things will still have to be manufactured the traditional way. "We're not going to be using this to make supertankers anytime soon," he said.
While Bowyer said some business models might be threatened by the rise of 3D printing, this was just a normal part of technological progress. "When was the last time you bought a roll of photographic film?" he asked the audience. "This entire industry has disappeared, almost unremarked and unmourned."
On the question of potential copyright infringement with 3D printers, Bowyer said he "had a little bit of sympathy" for copyright holders, but compared the situation with that of the music industry and digitisation. Musicians, he said, typically aren't too bothered about copying, because they make most of their money from live performances.
"The people who have been taken out of the mix are all the people who used to live in the middle and acted as a gateway between the musicians and the public. Now that connection can be made directly," he said.
In any case, intellectual property rights did not apply to the vast majority of objects people would want to make, according to Bowyer.
"There's no patents or copyright on teaspoons or coat hooks." he said.

Google finally launched its Glass Explorer programme in the UK on Monday, making its fabled wearable technology available to enthusiasts and developers in the region – albeit for a hefty £1,000.
Designed to help Google fix problems and develop the Glass technology before its wider global release, the Explorer Programme has been running in the US since 2012 and, according to Google, has massively improved the platform.
In fact, Google says the Explorer Programme has been such a success that the version of Glass V3 tried a year ago is archaic compared with the current version being sold in the UK. So when we were offered the chance of a fresh eyes-on look at Glass, we couldn't resist the chance to check on Google's progress.
Design and build
The basic Google Glass design hasn't been changed since we last tested it and the majority of the upgrades are software based.
This means in its basic form Glass has the same slightly futuristic-looking metallic frame with a power pack at its rear and a mini high-resolution display on its front.
While predominantly designed for use with voice commands, Glass also has the same trackpad feature on its right arm, which lets you turn it on with a tap, or navigate through the device's menus with up-and-down strokes. It also has a camera button that lets you silently take a photo or shoot a video using its 5MP 720p camera.
In the past, while we've found the bare-bones Glass version comfortable to wear, we couldn't escape the feeling that the device made us look very strange. Even if we wore them in Soho, one of London's quirkier areas, we'd still feel self-conscious.
But Google has inked deals with a number of frame manufacturers to make Glass more friendly for public use, and to make the frames look more like regular glasses.
At the Glass UK launch event we got to see a number of different frames and were impressed by how good a job they did to make Glass look more subtle. The frames ranged from regular office specs to 1980s Terminator-style sunglasses.
While the glass technology is still very prominent, the frames go a long way to make them less noticeable, which, as well as making us feel less conspicuous, will also make them less obvious to potential thieves. Considering their hefty price tag this is a very good thing.
Operating system and software
As before, Google Glass runs using a heavily customised version of Google's Android operating system and is designed to offer users a similar experience.
Powering it up by leaning our head back, we were able to perform a variety of tasks. These included searching for a picture online, taking a photo, getting directions using Google Maps and opening various webpages simply by saying "OK Glass" followed by a command.
To get directions, for example, we said, "OK Glass, King's Cross Station", and then tapped directions on the trackpad to launch the Maps app. Once open the app presented us with a dynamic map showing our current location. Impressively we found the icon showing our location actually reacted to where we were looking, making it easy to know which direction we should walk in to get to our desired Tube stop.
Glass is also confirmed to integrate Twitter, Facebook and Google Now to offer users dynamic push updates. Though, as we found with our first hands on, we didn't get a chance to see how Google Now works on Glass, as it wasn't connected to our Google account.
While the innate services on Glass are impressive, we were more interested in testing out the wealth of third-party applications on offer. Google has been trying to increase developer interest in Glass since it first came up with the idea. One year since we first tested the technology, we have to say we were impressed with some of the applications on show at the Glass UK launch.
While we didn't get a chance to try some of the more enterprise, healthcare and education-focused apps Google has been ranting about, we did see a wealth of interesting products, chief of which were Word Lens, Star Chart and Goal.com.
Word Lens is an innovative application designed to make Glass translate any text you're looking at. The app is currently available in a number of European languages including English, French, German, Spanish and Italian. We were impressed with how well it worked.
The app could be launched at any time simply by saying "OK Glass: translate". Once activated we simply had to look at the piece of text and tap the language we wanted it translated to using the trackpad. We found not only was Word Lens accurate, it was also very quick and was able to translate posters and information boards in seconds.
Star Chart is a free application designed to offer users information about the stars. It does this using an augmented-reality display that offers dynamic feedback and information on any constellation the user is looking at, or in the direction of. The information is displayed as text or as an audio file that's played using bone-conduction technology. This is similar to the technology used in some hearing aids and is designed to let Glass play audio without using traditional speakers or headphones, by transmitting sound through the bones of the skull to the inner ear.
The Goal.com application lets users set up custom information feeds about football. The feeds can be set to push updates about specific games, teams or leagues to the user via Glass. While the feature isn't of direct business benefit, unless you happen to be in the football industry, the app is a good example of how Glass could theoretically be used to keep up-to-date with news 24/7. For example, how useful would it be for any IT professional or business user to have a permanent feed pushing news updates and industry analysis from V3 on Glass?
Google says the display offers users an equivalent viewing experience to watching a 25in high-definition screen from eight feet away. Initially we found the screen was slightly blurry and difficult to use at the busy launch event, but we soon sorted this by altering the angle we were viewing it from using the hinge connecting it to the metal frame. The screen seemed no better to us than non-HD TV quality, falling short of current high-end smartphone displays.
Poor battery has been one of the key gripes coming from the Google Glass US test group, with many complaining that it dies in hours. We didn't get a chance to test the battery life, but the spokeswoman on hand told us she generally gets about four and a half hours of use before having to reconnect it to a micro USB charger.
One year on from our first encounter with Google Glass, we have to say we're impressed. While the updates aren't groundbreaking it's clear Google is getting some momentum in increasing developers' interest in the technology. Hopefully with Glass now available in the UK this will continue and we'll see yet more innovations and app-development projects in the very near future.

Retail giant Amazon finally unveiled its first ever smartphone, the Fire Phone, at a press conference in Seattle on Wednesday, ending months of speculation about its mobile plans.
Clearly having high hopes for the Fire Phone, Amazon has loaded it with a wealth of custom software and hardware features designed to differentiate it from existing handsets and help it carve a space for itself in the ever-competitive phone market.
However, even with Amazon's best efforts, if the Fire Phone is going to succeed in the top-end handset space it will first have to battle for attention with Apple's iPhone 5S – a feat that has proven beyond many smartphone makers.
Measurements and weight
Amazon Fire Phone: 139x67x8.9mm, 160g
Apple iPhone 5S: 124x59x7.6mm, 112g
Despite including some interesting design features, such as its four front cameras, the Fire Phone looks fairly unassuming compared with the iPhone 5S, and features a slightly chunky rubber-coated, not metal, frame.
The Apple iPhone 5S is also significantly lighter than the Fire Phone. Amazon claims the flipside of this is that the Fire Phone will be tougher than "average" smartphones. If true this could be a saving grace differentiating it from the iPhone 5S, which is prone to scratching and chipping.
Amazon Fire Phone: 4.7in, 1280x720, 315ppi HD LCD
Apple iPhone 5S: 4in, 1136x640, 326ppi Retina display
Amazon went to great lengths with the Fire Phone's display, loading it with custom Dynamic Perspective technology that it claims will offer users glasses-free 3D viewing experiences. Amazon has also worked to ensure the display is also great when it comes to picture quality, and claims the Fire Phone screen's 590 cd/m2 brightness and 1000:1 contrast ratio will let it match if not beat competing handsets, such as the iPhone 5S.
If true this will be a seriously impressive achievement as despite being slightly old, Apple's Retina displays are still among the best currently available.
Amazon Fire Phone: 2.2GHz quad-core Qualcomm Snapdragon 800
Apple iPhone 5S: Apple A7 chipset
When Amazon unveiled the Fire Phone, one of our biggest disappointments was its use of Qualcomm's previous-generation Snapdragon 800 chip. The use of the old chip, combined with the demanding software additions made by Amazon mean the Fire Phone may not match the performance of the iPhone 5S, which remains one of the fastest phones available. Still, we won't know this for sure until we've had a chance to properly benchmark and test the Fire Phone.
Amazon Fire Phone: Fire OS 3.5.0
Apple iPhone 5S: iOS 7
The Fire Phone runs on a heavily customised version of Android, which replaces pretty much all of Google's services with Amazon's and adds a wealth of custom features and applications. One of the biggest changes is the addition of Firefly.
Firefly is an information-gathering tool designed by Amazon, which lets you use the Fire Phone's camera and microphone to pull data from Amazon's database on a number of things including books, DVDs, phone numbers, QR codes, CDs, URLs, famous artwork and barcodes. If the feature works as well as Amazon claims, it could prove a key differentiator for the Fire Phone.
But even with these perks, if the Fire OS version is anything like the previous versions seen on Amazon's Kindle Fire tablets the iPhone 5S will be significantly more user friendly.
Amazon Fire Phone: 13MP rear camera with optical image stabilisation (OIS), f/2.0 five-element wide-aperture lens; 2.1MP front camera
Apple iPhone 5S: 8MP, f2.2 rear camera; 1.2MP front-facing camera
Amazon made a point to directly call out the iPhone 5S when discussing the Fire Phone's rear camera at the handset's launch event, claiming it will easily outperform Apple's flagship when it comes to imaging performance. If true this will make the Fire Phone one of the best camera options available in the Android ecosystem.
Amazon Fire Phone: 2,400mAh (11 hours of media usage)
Apple iPhone 5S: 10 hours of media usage
On paper the Fire Phone has a better battery life than the iPhone 5S. But companies' projected battery lives don't always ring true and many phones fall short of their listed times. As a result we won't know which phone has the better battery until we've had a chance to thoroughly test the Fire Phone.
Amazon Fire Phone: 32GB, 64GB
Apple iPhone 5S: 16GB, 32GB, 64GB
The Apple iPhone 5S comes with more internal storage options than the Fire Phone. However, its physical storage lead is countermanded by Amazon's decision to offer Fire Phone users unlimited space on its Amazon Cloud Drive storage service.
The Amazon Fire is due for release in the US on 25 July with prices starting at $200 on a two-year contract with AT&T, and $649 SIM-free. This indicates that if Amazon does choose to release it in the UK, the 32GB Fire Phone will be at least £450 SIM-free. While steep, this means the Fire Phone could still be cheaper than the iPhone 5S; its equivalent 32GB version retails for £629.
On paper the Amazon Fire Phone does have the chops to take on the Apple iPhone 5S. While it features a less alluring design and runs using a previous-generation processor, its 3D display technology and Firefly information service make it one of 2014's most interesting handsets. Whether this will be enough to entice buyers away from its more established and ever-popular Apple competition however, remains to be seen.

Samsung has described its new Galaxy Tab S, unveiled in New York earlier in June, as "industry-leading" when it comes to specifications. In light of the fact this was probably a dig at Apple's iPad Air, we've pitted the two tablets head to head on paper, to see which one offers the best features.
iPad Air: 240x169.5x7.5mm, 478g
Galaxy Tab S: 213x177x6.6mm, 465g
When Apple first unveiled the iPad Air, it was keen to boast that it was – at 7.5mm thick – the thinnest tablet available on the market. But Samsung has stolen the crown, with the Galaxy Tab S measuring a mere 6.6mm. Samsung's latest tablet, despite its larger screen size, is slightly lighter too, with the 3G and 4G versions tipping the scales at 465g and 467g, respectively.
iPad Air: 9.7in, 2048x1536, 264ppi LED-backlit in-plane switching (IPS) screen
Galaxy Tab S: 10.5in, 2560x1600, 288ppi Super Amoled screen
The iPad's screen – since the release of the third-generation model at least – has long been heralded as one of the best, with its Retina display boasting 2048x1536 resolution.
Samsung, however, has once again toppled Apple's flagship device, with its 10.5in Galaxy Tab S boasting a higher, "industry-leading" 2560x1600 touchscreen display. The screen also has Samsung's Super Amoled technology and a 100,000:1 contrast ratio, which should make for deep blacks and bright whites.
However, given that the screen on the Galaxy Tab S is larger than Apple's 9.7in, it remains to be seen which comes out on top in terms of quality.
It's worth noting that the Samsung Galaxy Tab S is also available in an 8.4in model with the same 2560x1600 resolution, pitting it against Apple's latest iPad Mini tablet.
iPad Air: iOS 7
Galaxy Tab S: Android 4.4 KitKat, custom UI
It's always hard to judge a winner in the software category when comparing an Apple and a Samsung device, as most people already know whether they prefer iOS or Android.
The iPad Air runs Apple's latest iOS 7 release, and will be promptly updated to iOS 8 once this is released later in the year. Samsung’s Galaxy Tab S runs the newest version of Google's Android 4.4 KitKat mobile operating system, which it has heavily customised in its own user interface (UI).
Fans of the vanilla version of Android might not be too keen, as Samsung's custom UI sees the tablet's 10.5in screen stuffed full of widgets, custom applications and features. However, some of these will likely come in handy, such as Samsung's S Note app, the ability to answer a call through the tablet and its support for the tablet's on-board fingerprint scanner, adding an extra layer of security to the device.
Despite appearing on the flagship iPhone 5S, the iPad Air doesn't come with a Touch ID sensor.

Amazon has been trying to fully break into the hardware scene since the launch of its first Kindle e-reader. Yet, to date, despite the success of the Kindle, and the launch of its subsequent Kindle Fire range of tablets, for years there's been one serious gap in Amazon's portfolio – its lack of a smartphone.
Last night Amazon plugged this gap, unveiling its first-ever smartphone, the Fire Phone. Featuring a number of innovative software and hardware features, including a glasses-free 3D display, the Fire Phone has sparked debate within the smartphone industry, leading many to question how it will fare in the increasingly competitive market.
Apart from the Fire Phone's four front-facing cameras, Amazon's handset is fairly unassuming in its look and features a rubber frame, Gorilla Glass front and anodised aluminium buttons on its sides.
Amazon claims that, while the Fire Phone isn't waterproof and dustproof, like many of the recent IP-certified top-end Android smartphones we've seen this year, it is tougher and significantly more scratch resistant than the average handset. This could prove a key selling point differentiating it from key competitors, such as the HTC One M8 and Sony Xperia Z2, which are both prone to picking up marks.
A consequence of the Fire Phone's "tough" design is that it is thicker and heavier than competing handsets in its size bracket, measuring in at 139x67x8.9mm and weighing 160g. The Fire Phone's weight could be an issue for smartphone users who are accustomed to feather-light handsets, such as the 112g iPhone 5S.
The Fire Phone's 4.7in HD LCD 1280x720 315ppi screen is one of its most interesting features, with its custom Dynamic Perspective technology. This is designed to offer users glasses-free 3D viewing experiences in key applications, such as maps, the Fire Phone web browser and e-reader.
Amazon claims it creates the 3D effect by tracking the user's iris and head movements via the four front cameras and adjusting displayed images accordingly. If the technology works as well as Amazon claims, it could prove a key selling point for the Fire Phone when it is released. But its long-term appeal will be decided by how many application developers choose to take advantage of the functionality and use the newly released Amazon Dynamic Perspective software development kit (SDK) to make apps for the phone.
The Fire Phone runs using Fire OS 3.5.0. Fire OS is a heavily customised version of Google's Android operating system (OS) that radically redesigns the menus and pushes Amazon's Video and Music, Kindle Store and Newsstand to the front of the user interface. The OS also adds a number of custom-made Amazon applications, one of the most interesting of which is the Fire Phone's Firefly service.
Firefly is an information-gathering feature that can be activated anytime using a physical shortcut key. At a basic level Firefly uses the Fire Phone's rear camera to recognise and draw information from Amazon's database on a number of sources including books, DVDs, phone numbers, QR codes, CDs, URLS, famous artwork and barcodes. Amazon claims that the feature is so advanced it can also be used for contact-building, as it can obtain information such as phone numbers and email address from business cards, fliers and advertisements.
Firefly can also use the Fire Phone's microphone to access information on music or television shows as they are playing.
While some privacy advocates, such as anonymous communications firm Silent Circle, have questioned Firefly's potential snooping and profiling powers, the feature could be particularly useful for regular networkers, or those who often shop on Amazon.
When it comes to processing power, the Fire Phone does lag slightly behind most other 2014 flagships, coming loaded with last year's 2.2GHz quad-core Snapdragon 800 CPU and featuring 2GB of RAM. Considering the fact that the newer Snapdragon 801 processor has been out for quite some time now, we're a little disappointed about the Fire Phone's use of an older chip.
Amazon made a big deal about the Fire Phone's 13MP rear-facing camera, claiming its multi-frame HDR, auto-focus, optical image stabilisation, f/2.0 five-element wide aperture lens and LED flash technologies will help it easily outperform competing top-end handsets. This is a pretty big claim considering the wealth of top-end camera phones to arrive this year, which currently include the Sony Xperia Z2 and Samsung Galaxy S5.
The Fire Phone is powered by a 2,400mAh battery, which Amazon lists as offering up to 11 hours of video playback off one charge. If true the Amazon Fire will have above-average battery life compared with most other smartphones, which usually offer between six and seven hours of video playback during our battery burns.
The Fire Phone is available with either 32GB or 64GB of internal storage. Most users won't have to worry about running out of space with either option, as Amazon has bundled the Fire Phone with unlimited free space on its Amazon Cloud Drive storage service.
The Amazon Fire is due for release in the US on 25 July, with prices starting at $200 on a two-year contract with AT&T or $649 SIM-free. There is currently no word on when and if it will be released in the UK, but the US price indicates that it will be around £450 SIM-free if it does.
At first look, the Amazon Fire Phone is very interesting. The Fire Phone includes a number of features that have never been seen before on a smartphone, such as its Dynamic Perspective screen technology and Firefly service. But it also features a few flaws that could put off smartphone buyers, such as its slightly heavy, boxy design and use of a previous-generation Qualcomm chip.
This makes it difficult to know how the Fire Phone will fare in its battle to draw interest from more established smartphones. Considering the Kindle Fire tablet's lukewarm reception, the potential privacy issues and the price tag, Amazon is likely to face an uphill struggle to push uptake of its smartphone.

Sony kicked the tech year off with a bang, unveiling a fresh wave of Xperia smart devices that many observers have considered to be its most innovative to date.
One of the best of these was the Xperia Z2 Tablet. Featuring a sturdy yet slim design, a wealth of top-end components and up-to-date Android software, the Xperia Z2 Tablet remains one of the best Android tablets currently available.
But a few months on, Samsung has returned to the tablet scene with its upgraded Galaxy Tab S, leaving many buyers wondering if Sony's day in the sun as leader of the Android tablet market is already over.
We've pulled together the key specifications from both devices here to see which is the daddy, at least on paper.
Galaxy Tab S: 213x177x6.6mm, 465g
Xperia Z2 Tablet: 266x172x6.4mm, 439g
Both Samsung and Sony designed their respective tablets to be as light and thin as possible. In this area Sony is the clear victor, with its Xperia Z2 Tablet being over 20g lighter and 0.2mm thinner than the Galaxy Tab S.
The Xperia Z2 Tablet is also better in terms of build quality, at least on paper, carrying IP55 and IP58 certifications so it can survive an accidental submersion in water.
Galaxy Tab S: 10.5in, 2560x1600, 288ppi Super Amoled
Xperia Z2 Tablet: 10.1in, 1200x1920, 224ppi TFT capacitive touchscreen
Neither the Galaxy Tab S or Xperia Z2 Tablet's display breaks the 300ppi count, but the Samsung tablet's screen is superior on paper.
Outside of its higher pixels-per-inch density, this is largely due to the use of Super Amoled technology. This lets screens display richer colours and deeper blacks, by electrically charging each individual pixel to generate colours and creating blacks by turning off the relevant pixels.
Galaxy Tab S: Android 4.4 KitKat
Xperia Z2 Tablet: Android 4.4 KitKat
Both The Xperia Z2 Tablet and Galaxy Tab S run using customised versions of Android. However it's worth noting that Sony's appraoch shows a much lighter touch than Samsung when skinning the Xperia Z2 Tablet, with the only notable changes being the addition of a few custom applications, such as the PlayStation Store.
Samsung has taken a heavy-handed approach to skinning the Galaxy Tab S and has completely reworked the user interface, installing a number of custom software services. These include multi-window support, multitasking and a new software service that lets users answer incoming calls to their mobile phone via the tablet.
Galaxy Tab S: Exynos 5 Octa (1.9GHz quad-core and 1.3GHz quad-core)
Xperia Z2 Tablet: Quad-core Qualcomm Snapdragon 801
The Xperia Tablet Z was amazingly fast and scored an impressive 35573 using the Antutu benchmark. By comparison, Samsung's other Exynos 5 Octa-powered tablet, the Galaxy Note Pro 12.2, scored a slightly lower 32727 on the same test, indicating that the Galaxy Tab S may also be a fraction slower.
We'll be interested to see how the Xperia Z2 Tablet and Galaxy Tab S perform head to head in our full head-to-head review coming soon.
Galaxy Tab S: 8MP rear, 2.1MP front
Xperia Z2 Tablet: 8.1MP rear, 2.2 MP front
On paper, both the Galaxy Tab S and Xperia Z2 Tablet are fairly evenly matched when it comes to camera technology. We'll only know which performs better when we get a chance to put the two tablets head to head with real-world testing.
Galaxy Tab S: Non-removable lithium polymer 7,900mAh battery
Xperia Z2 Tablet: Non-removable lithium polymer 6,000mAh battery
The Galaxy Tab S has a slightly larger battery than the Xperia Z2 Tablet and is listed by Samsung as offering users "above-average battery life". If true this could be a key differentiator, as the Xperia Z2 Tablet lasted for around eight to nine hours of multimedia use in our review, which by tablet standards is fairly average.
Galaxy Tab S: 16GB, 32GB, expandable by up to 128GB via micro SD card
Xperia Z2 Tablet: 16GB, expandable by up to 128GB via micro SD card
The Galaxy Tab S comes with more internal storage options than the Xperia Z2 Tablet. But both tablets can have a further 128GB of space added via their respective micro SD card slots, so most users shouldn't have to worry about running out.
Galaxy Tab S: £420
Xperia Z2 Tablet: £399
Despite offering on-paper equivalent specs to the Galaxy Tab S, the Xperia Z2 Tablet is £20 cheaper, with prices starting at £399.
When viewed from a purely technical perspective both the Xperia Z2 Tablet and Galaxy Tab S are fairly evenly matched. Both tablets feature powerful processors and ultra-slim, lightweight designs. Hopefully the Galaxy Tab S will make good on its promise when it is released later this year and buyers will have a second viable top-end 10in Android tablet to choose from.

18 Jun 2014
Apple and Samsung have been fighting for control of the tablet market for some time. But despite Samsung's best efforts, it has traditionally been Apple's iPad tablets that have ended up as each year's top-selling device.
Unperturbed by Apple's past successes Samsung has returned to the battleground in 2014, unveiling one of its highest-specced tiny tablets ever, the Galaxy Tab S 8.4.
Featuring an ultra-thin design and wealth of top-end hardware and software, the Galaxy Tab S has caught the eyes of many buyers, including us. But, to make good on its promise, the Galaxy Tab S will first have to overcome its key rival, the iPad Mini 2, which has become a benchmark in many buyers' eyes.
Galaxy Tab S: 213x126x6.6mm, 294g (WiFi)
iPad Mini 2: 200x135x7.5mm, 331g (WiFi)
In a move many have taken to be a clear swipe at Apple, Samsung designed the Galaxy Tab S to be as thin and light as possible. As a result the Galaxy Tab S is both thinner and lighter than the iPad Mini 2.
The Galaxy Tab S also has a radically different design to the all-metal iPad Mini 2, featuring aluminium sides and a perforated polycarbonate back. So despite being lighter and thinner, the Galaxy Tab S may not be as sturdy as the purely metal iPad.
Galaxy Tab S: 8.4in 2560x1600, 359ppi Super Amoled
iPad Mini 2: 7.9in 2048x1536, 326ppi Retina display
Apple has always claimed its Retina display technology is the best currently available. Traditionally, at least in the tablet market, there has been some truth to this claim and the iPads' Retina displays have always been superior to the screens on Android devices.
Samsung has worked to fix this on the Galaxy Tab S, loading it with its own Super Amoled screen technology. Super Amoled technology works to let screens display deeper and richer blacks by electrically charging each individual pixel to generate colours, meaning it can create blacks simply by turning off the relevant pixels.
Galaxy Tab S: Android 4.4 KitKat
iPad Mini 2: iOS 7
The Galaxy Tab S comes loaded with a customised version of Google's Android operating system (OS). In the past we've found Samsung's changes have sometimes been to the detriment of the OS and have made devices significantly less user-friendly than their iOS competitors. Hopefully this won't prove true with the Galaxy Tab S.
Galaxy Tab S: Exynos 5 Octa
iPad Mini 2: A7 plus M7 coprocessor
When it comes to performance, we've always found picking between iOS and Android handsets quite difficult. This is because iOS system requirements are significantly lower than Android and allow Apple devices to match or beat the performance of competing Google devices with higher on-paper specifications. Because of this we won't be able to know which tablet performs better until we thoroughly test the Galaxy Tab S.
Galaxy Tab S: 8MP rear, 2.1MP front
iPad Mini 2: 5MP iSight rear and 1.2MP FaceTime HD front
Cameras have always been one of the iPads' weakest points, and sadly this remains true on the iPad Mini 2. The basic 5MP rear camera is capable of at best average imaging quality, even when shooting in regular light. Given other Samsung tablets' superior cameras, we think the Galaxy Tab S will outperform the Apple iPad Mini 2 when it comes to imaging performance.
Galaxy Tab S: 16GB, 32GB, expandable via micro SD up to 128GB
iPad Mini 2: 16GB, 32GB, 64GB, 128GB
The iPad Mini 2 is available with more internal storage options. However, the Galaxy Tab S is the only one of the two that has the option to upgrade its storage.
Galaxy Tab S: 4,900mAh (11 hours)
iPad Mini 2: 10 hours
Samsung's 11-hour multimedia playback score means the Galaxy Tab S should last an hour longer than the iPad Mini 2, which is listed as offering 10 hours of life off one charge.
Galaxy Tab S: £329
iPad Mini 2: £319
Apple iPads have always carried a premium price tag and are generally significantly more expensive than their Android competitors. Interestingly, though, the iPad Mini 2 is cheaper than the Galaxy Tab S, with prices for the basic 16GB WiFi model starting at £319. Pricing for the equivalent Galaxy Tab S starts at £329.
On paper the Galaxy Tab S 8.4 is a very impressive machine and generally beats the Apple iPad Mini. We'll be excited to see if the tablet makes good on its early promise, so look out for our full review later this year.

Samsung's been working hard to get a stronger foothold in the tablet market for some years now. Yet despite its best efforts, as noted by SAP global vice president of mobile strategy Bill Clark during an interview with V3, most companies are still favouring Apple's iPads over Samsung's Galaxies.
Aware of this Samsung has come out swinging with its latest flagship Galaxy Tab S 10.5 tablet, kitting it out with a number of top-end components and software features that on paper make it one of the most business-friendly Android devices ever made.
In a clear swipe at Apple, Samsung has designed the Galaxy Tab S to be thinner than the 7.5mm iPad Air at just 247x177x6.6mm. The Galaxy Tab S is also very light, with the WiFi model weighing 465g and the LTE model 467g.
The Galaxy Tab S sports a similar design to the Galaxy S5, coming with a slightly rubberised perforated back, metal sides and custom fingerprint scanner built into its physical home button.
If the scanner performs as well as that on the Galaxy S5's it will be a definite bonus to businesses, making it easier to secure data stored on the tablet should it be lost or stolen.
Samsung made a big deal about the 10.5in 2560x1600 Super Amoled touchscreen of the Galaxy Tab S, describing it as "industry leading" during the tablet's launch. Specifically, Samsung claimed the screen's 100,000:1 contrast ratio will let the Galaxy Tab S display deeper blacks and brighter whites than rival tablets.
Considering our past experience with Samsung's Super Amoled screens, this may well be true. Super Amoled is a custom version of the traditional Amoled screen technology. Basic Amoled technology is designed to let screens display deeper and richer blacks by electrically charging each individual pixel to generate colours, meaning it can create blacks simply by turning off the relevant pixels.
The downside of this is that the technology reduces battery life and increases the device's thickness as it requires manufacturers to place the capacitive layer - the component that senses touch - on top of the main display. Super Amoled fixes this by integrating the capacitive touchscreen layer directly into the display, reducing its thickness and making it more power efficient.
The Galaxy Tab S runs using a heavily customised version of Google's Android 4.4 KitKat mobile operating system. The custom skin added by Samsung radically reworks the operating system's user interface and adds a number of custom services and applications, including multi-window support, multitasking and a new software service that lets users answer incoming calls to their phone using the tablet.
The Galaxy Tab S also features Papergarden and Kindle for Samsung applications. Papergarden is a custom app designed for viewing digital content, while Kindle for Samsung lets Galaxy Tab S users download a free book each month.
While these additions sound good, in the past we've found Samsung to be rather heavy-handed with its software and can make its device UI feel a little cluttered. We'll only know if this is the case on the Galaxy Tab S when we get our hands on it and actually test it.
The Galaxy Tab S is powered by Samsung's own Exynos 5 octa-core processor and features 3GB RAM. This puts it on a par with Samsung's Galaxy Note Pro 12.2, which features the same specifications. This is no bad thing as in the past we've been impressed by the performance of Samsung's octa-core processors.
As an example, the Galaxy Note Pro 12.2 scored 32727 on the Antutu benchmark, putting it well above most other 10in tablets when it come to performance. In comparison, the Google Nexus 10 scored 13483 on the same test. If the Galaxy Tab S matches this it will be one of the fastest tablets available on its release in July.
Traditionally, camera technology is one area where tablets have lagged behind their smartphone siblings. This remains true on the Galaxy Tab S, which features basic 8MP rear and 2.1MP front cameras.
The Galaxy Tab S is powered by a 7,900mAh unit that Samsung claims will "let you enjoy hours of entertainment". We won't be able to know how good the Galaxy Tab S' battery is until we've thoroughly tested it.
The Galaxy Tab S will be available with 16GB or 32GB of internal storage. Both versions can have a further 128GB of space added via their microSD card slots.
Samsung is yet to disclose the Galaxy Tab S UK price, though in the US pricing for the 10.5in model starts at $499, putting it on a par with most other top-end 10in tablets.
On paper the Galaxy Tab S is a very impressive machine. Featuring a top-end Super Amoled display, powerful octa-core processor and wealth of custom software features, the Galaxy Tab S has the potential to be one of 2014's finest Android tablets. We'll be interested to see if the Galaxy Tab S makes good on its early promise when we put it through its paces for our full review later this year.
