Personally I feel XP is the best Microsoft product ever...
Its true that DRIVERS are a problem...
even if XP says a particular driver is NOT compatible, be sure to check the web site of the manufacturer..
Even if you install a hardware which XP says is not safe, you can easily uninstall it using the "safely remove hardware" option (it will be there in your system tray)
I have personally installed a few hardware like that (no problems till now)
By the way, the driver for 2000 is most likely to work in your XP.
Again those of you like additional features, be sure to check out "XP Plus" - its kinda nice
