The Asus Transformer Pad Prime tablet made a big splash when it launched into the UK market at the start of this year, quickly earning a reputation as the best Android tablet available.
Since then, Asus has released its follow up model, the Infinity. The Infinity retails for £100 more than the Prime, despite at first glance looking almost identical. This has lead many to wonder, is it worth the extra cash?
Design and build
To a casual observer the Prime and Infinity must look very similar indeed, featuring dockable keyboard attachments, a brushed metal finish and almost identical 10.1in displays.
Visually, the only factor separating the Infinity from the Prime is its slightly darker casing, and very slight weight and thickness increase; the Prime weighs 586g and is 8.3mm thick while the Infinity is 598g and 8.5mm thick.
This means that the Infinity does feel slightly heavier when held, but not so much so that it feels cumbersome against the Prime.
The fact that Asus hasn't chosen to radically change its design for the Infinity is unsurprising, as the two both feel incredibly well built.
As well as giving the tablets a suitably high end feel, we found during testing that the metal casing of both devices is there for more than pure visual allure, making them tough as nails and more than capable of dealing with the odd bump and scrape.
They're both pretty much identical design-wise
The Prime features a 10.1in Super IPS+ display with a 1280x800 resolution, while the Infinity packs a 10.1in Full HD 1080p, 1920x1200, Super IPS+ screen that boasts 224 pixels per inch.
Comparing the two found we found that the Infinity's screen really did feel like a step up, coming close to matching the stunning retina display featured on Apple's new iPad.
With the same Super IPS+ technology that let the Prime overshadow the iPad 2 in January, we were impressed with Infinity's display performance. We found that its high brightness levels allowed it function surprisingly well outdoors, even in bright sunshine.
The screen viewing angles are also incredible. When set at full brightness with IPS+ switched on, we'd rank it as one of the best screens currently on the market.
Winner: The Infinity
The screen is the best seen on any Android tablet, ever
