The screen on the nexus 7 isn't much bigger than some of those large phones out there now. With the large menu bar at the top and the virtual buttons at the bottom its nearer a 6 inch tablet. I spent a good while today playing with the tablets in my local Tesco - the screen on the Mini is gigantic compared to the Nexus. And why is the Apple environment bad, but the Android / Windows is not? Silly.
The Apple environment is very different from the Android environment. Silly.
(I cant speak for the Windows 8 environment)
