Usually when we referto Windows 8 it's normally a tablet, smartphone or even notebook. What about something a lot bigger though?
Wired.co.uk claims that Steve Ballmer, CEO of Microsoft has in his office an 80 inch touch screen with Windows 8. The leak supposingly came from the vice-president Frank Shaw who seems to have stated that ' Steve  Ballmer has a huge 80 inch Windows 8 touch-screen. He through away his phone and notebook and hang the screen it on the wall.' A while back at the CES 2012 Sharp presented their own 80 inch touch screen but Shaw claims Ballmer's screen isn't manufactured from Sharp.
