@ DoomMaster's "Windows XP is the anti-christ" posts
Hmm, I think you'll need to back up your claims about services blocking WinXP. According to the stats for my website, WinXP is the most popular OS in use nowadays. I seriously doubt services will block it.
IMO there are a few sucky things about WinXP, so I stick with Win2k (not really out of choice, new mobo didn't support NT4), but nothing seriously bad. Service packs and WinXP don't seem to agree far more often nowadays, and I don't like Windows Product Activation, nor IM being part of the OS.
