Windows XP upgrade???

I think that Im just going to keep 2000 on my laptop and borrow my buddies old copy of 98 with a key and update my desktop to xp just because I have it and I might as well use it.
Everyone on this board and 2 other copmuter boards have pretty much all said the same thing "why bother, whats wrong with 2000?" and to be honest...nothing, Im current on all my updates for 2000, it's working fine and all my games and programs seem to like it so I might as well keep it.
If it aint broke don't fix it... unless it's a car and we all know how that one goes.
Thanks for all the replys and info guys!!!
