I current have a system that can support running Windows XP Pro (but now running WIN98SE), but I am unsure if I want to spend the money to upgrade to XP-PRO, of if I want to spend the money to get a DVD-RW drive for the same amount.

Any suggestions?

If I go to XP I get to break the 4 GB limit (which is useful). If I get a DVD-RW drive I get to store more files externally in formats more useful to others.
