Well, XP looks better
There's no big difference between XP and 2000, but XP kicks bum over win98/me. First of all it's built on the Win NT kernel which makes it much more stable than Windows 98/me. It has a crap load of new features (Remote Desktop, integrated passport, too many to list) however it's a huge memory hog. Definitely not intended for slow computers.
Also, I noticed quite good driver support with Windows XP. It found everything I had (printer, modem, scanner, video.)
With windows 98/me I had to put in driver disks which was an inconvinience.
Well, hope this helps
