A co-worker's son installed that, just to have the latest. Uninstalled it very soon after. Dog slow.
Our house's Wintel machines are all Win98 with one Win2k. The XP Pro box has been opened but never installed.
I've been running XP Pro on this box since the summer of 2002 and it's been just fine. The only complexity I ran into was when my hard drive failed. I had a 120G drive that I imaged over to a 160 as a backup with the thought that I could just swap in the backup if the primary failed. Bill says "No" and the upshot was alot of headaches and hacking, but I think it's the same with Win2K, too.
