Bless you, brave guinea pig! The info I've seen about Windows 8 has not been appealing. The kindergarten user interface (sorry, just my reaction to screenshots) looks way less useful than WinXP-Win7. Touchscreen? Why? I'm supposed to lean over my keyboard and mouse to reach the screen? Looks like another Vista (if not ME) in the offing. Microsoft seems to come up with a clunker every other version of Windows. Makes you wonder if they have two separate teams working on it.
But all that is curmudgeonly prejudice more than anything else. Let us know how it goes, brave GP! It'd be interesting to have opinions from someone who's actually tried it.
