Bugbear: I upgraded from Vista to Windows 7 (64-bit) a few months ago. No problems so far. It's noticeably more responsive than either Vista or XP. Just stay away from Windows Live - really strange! Sometimes I think MS is trying to get folks off of it onto something else, like Outlook.

I still run XP on my laptop, but will probably upgrade the hardware before the OS. Good luck with acclimating. I wonder if MS has an official tartan? ;-)
