I really don't see why people rage on vista so much. I used it, never had a problem. I haven't tried 7, but it looks like if I want to get a new desktop, that is the way to go.
As for XP...it's really just a clunkier, bulkier version of 7.
You see, windows XP is like the CGI in the first tron movie.
Windows 7 is the new remake (the CGI part...)
I like vista. some people do, some don't, People who know what they are doing, get 7. People who think they know what they are doing use XP, and people like me who use vista, Just don't really give a hoot because we aren't on the computer all of the time.
