4. Microsoft Surface RT
Microsoft surprised the world earlier this year when it announced plans for its own tablet devices to showcase the capabilities of its Windows 8 platform, which launched at the end of October.
Of the two Surface devices unveiled, only the Surface with Windows RT is currently available, which is powered by an ARM-based Nvidia chip in place of the more conventional Intel processor.
This delivers a more appliance-like experience than the full Windows 8, and also means that the Surface RT really can be used for an entire day running on batteries.
But the real selling point of this tablet is that it comes with Microsoft's Office 2013 apps built-in as standard, making it a great device for editing and viewing documents on the move.
When combined with the optional Type Cover, which provides a full Qwerty keyboard, the Surface can easily replace a laptop for many users.
On the downside, Windows RT means that standard Windows applications will not run, with users restricted to "Metro-style" apps designed for the new user interface. However, the Surface is a worthy contender for one of the best tablet devices of 2012 - if you can get past the new-style user interface.
3. Google Nexus 10
It's no secret that Samsung currently rules the roost when it comes to smartphones.
The company's Galaxy series of smartphones are some of the most popular in the world, with most analysts estimating Samsung currently owns roughly a third of the smartphone market.
Yet, the Korean giant is yet to repeat its success in the tablet market, which is why we were surprised when Google ditched Nexus 7 maker Asus in favour of Samsung for its latest 10in Nexus 10 tablet earlier this year.
However, once we got our hands on the device, all became clear as the Nexus 10 is an absolutely fantastic bit of kit, featuring a host of great features that prove Samsung can definitely cut it in the tablet arena.
Key features include its brilliantly crisp and bright 10in 2,560x1,600 resolution screen which is one of the best on the market and the ability to run multiple user accounts off the device.
With prices starting at a meagre £319, the Nexus 10 is a strong alternative for any tablet fan looking for an alternative to the Apple iPad.
