“Steve Ballmer has an 80-inch Windows 8 tablet in his office. He’s got rid of his phone, he’s got rid of his note paper. It’s touch-enabled and it’s hung on his wall.”
We don’t even know if this can be legitimately called a “tablet” — I think “television” is more suitable — but it’s pretty awesome nonetheless. No word on consumer availability for this monstrosity of a tablet, but it would presumably be later this year if it is ever publicly released.
