Windows 8.... I love all the negativity it has produced, a tablet interface on a pc just for me doesnt work. Oh and the surface is a gimmick, comes in two versions and specs. The £400 one has windows RT, which does not allow external apps to be installed only apps from marketplace. The other surface tablet has a bigger spec and runs win8 pro which will allow external apps.
For the price you can just buy a asus eepad (eg transformer) or a all-in-one pc for the same money at a 21-22" spec, however yet again using the ghey metro on a big screen is a no no, why windows has forced a pc to be like a tablet has baffled me, so much that I've started looking at imacs for the future

Now off to use a real device... a snes or a pc with win7
