Well, pretty much just a "me too" post. IIS 6 is far superior to IIS 5 so for web apps there's no reason to keep Windows 2000 Server around (all I use is Windows Server 2003). And for the workstation, I much prefer Windows XP Pro to Windows 2000. I own my own (very small) business, though, so my 'enterprise' decisions are pretty easy, but Windows 2000 hasn't been a part of my architecture for several years.
