If you ask me: Don't do anything with XP, i've tried to install XP on the same type PC. Not funny, loads of probs with drivers and so on. I would wait a few days for the RC of windows 7. Upgrade instead of downgrade. I've got the beta of W7 (7000 build) running on the (old) laptop, and works like a charm. Almost no probs with drivers (at least i haven't had one, nor have any of friends or "customers"). But if you are into challenges; go on! My 2 cents.
