Upcoming gadgets of 2012 – Apple iPad 3

No surprises here – you voted the iPad 3 your most wanted future gadget in the 2011 Stuff Gadget Awards. From the moment Apple launched the iPad 2, iPad 3 speculation has been in serious overdrive.
2011 saw some great efforts from the Android camp, including Asus' original Transformer (winner of the Stuff's 2011 Product of the year award), and Samsung's Galaxy Tab 10.1 – but we're expecting Apple's next iPad effort to take things to a whole new level.
An eye-slicingly sharp 2048 x 1536 pixel 10in screen, a quad-core Tegra 3-baiting A6 processor and a carbon fibre case are just some of the rumoured specs for the iPad 3 that could see it setting the gold standard for tablets once again. Previous iPad launches point to a February or March release, so we're hoping it'll be putting in an appearance soon.
