Personally I think Windows 7 will be a hit.
Watching those videos is so painful. It’s like listening to some kid’s parents trying to be hip and cool by using words such as “bodacious” and “radical”.
I’ll be sticking with XP in the foreseeable future. I’d switch to Ubuntu or something, but I have a bunch of obscure, Windows-only games I play (which may or may not Wine well, especially if they’re Japanese like the Touhou games).
