OK already, enough bashing XP. It's not that bad.. In fact, it can be quite good. I'm not a system admin, so I probably don't have the needs you guys might have. But the one thing that XP does that the others don't is "it just works"

. hehe. When I install it, it recognizes all of my components, and I don't need to install many drivers. Sure you want to get the latest vid drivers, etc., but since XP recognizes my NIC, and automatically configures my high-speed internet (with no driver or app CDs), downloading the latest drivers can begin as soon as Windows comes up.
I also like the customizeability (is that a word?) of the GUI. The green start button may be ugly, but you can change it..
I find it to be quite stable.
Also, I tried installing W98se on one machine for video editing. All of the hard drives were on a SCSI 160 controller. I couldn't find a way for the installer to recognize my drives... I got W2K, and that worked, but I needed to hit F6 and install extra drivers... WXP just worked.
The built in features like CD Burning are a bit too simplistic for our use, but they do in a pinch.
