Have to agree about the "day late" feel, price being a potential issue - and somewhat about the keyboard, though it's the same concept as my brother's Android tablet (and his cover with a keyboard built in) - just as flat, but for quick input now and again, works fine.
I can't help but wonder if having two versions of the tablet (RT and Pro) isn't going to end up coming back to bite them, though. "My Windows 8 tablet can't run XYZ!" "Sure, mine can!" Cue call to tech support for "broken" tablets... or maybe I'm just pessimistic.
As much as I don't like Win8 on the desktop, I am looking forward to seeing how it behaves and feels on a tablet.
