Now, can someone explain to me why I should get XP, others than "its there".
Because you're a gamer and modern games no longer run on win98. I upgraded a year and a half ago and don't really have any regrets. I'd like to be able to play a few older DOS games but it's not the end of the world. Stability is the big advantage, the only crashes I ever get are heat related where as in WIN98 I recall having a crash pretty much daily.
