Windows 2000 is probably the best OS MS has ever made.
I would have to disagree, at least from a gamers standpoint. I have loved XP as it can play games and it is actually stable!!! (well, most of the time) I can actually go a few weeks without restarting. I also like the multi-tasking, I have been playing RTCW while watching a DVD on my second monitor, burning a CD, and listening to MP3's (no, this is not normal for me, I was just trying to crash my machine) It does have issues, but it is my fav MS OS by far as you can game and get work done on it. I got tired of the 98/2k dual boot setup so this is really nice. Oh course, this is all IMO
