I upgraded my Dimension 8100 from ME to XP about a year ago and I can tell you the advantage is the reliability and trouble free operation of XP and the negative is the fact that some software programs do not work as before in XP or some wont work at all, also there are some compatability issues with some hardware such as printers and scanners. I would research the hardware compatability of all hardware "BEFORE" purchasing XP. A search on Microsoft web site should answer all questions about hardware compatability.

srandy,

As marasco10 stated, XP is a much more stable system than ME and it also makes better use of installed RAM. You should run the Windows Upgrade Advisor (available here) to see what installed hardware and software will not be supported under XP.

You should have a minimum of 256MB RAM to run XP and should update your BIOS to the latest available before upgrading.

That being said, if you are able to run all of your applications under ME without problems such as frequent low memory warnings and/or crashes, there is no compelling reason to make the move.
