Ironically, the VivoTab RT was easily among the best RT devices. And I still think they’re good enough for most people — but they clearly aren’t selling, and my take is that they’re both too different (thanks to the Windows 8 effect) and too crippled (people think RT is “less” than Windows, and the bundled “preview” app suite doesn’t help). I’m really curious as to what that means for Office 365, too.
