Have Xp on as well but rarely if ever use it, Win 7 is my primary OS at the moment. Just installed RC build 7127. I think once Win 7 is finally released later this year, XP users who try it, will feel safe in adopting it as their primary OS. I was a huge fan of XP, never really used Vista(due to all the bad feedback from friends) but so far I am impressed with Win 7. Have been using the Betas and now the RC for at least a month or so.
