yeah i got the betas like 5 months ago from a student at the university of florida and got a final version a month ago, but went and bought it yesterday. it is SO much better than 98, it's alot faster and alot more stable. the only thing i don't like is that my puter looks like a fisher-price toy, also some old games don't work well. and from what i hear not all devices work with xp. but all of mine do. do you need it??? yes, YES, YES!!!! it hasn't even locked up on me once. if your really not sure...wait for the first service pack then get it
