Well, I use XP still, and from what performace i have seen gtom W7, it is going to be awesome! Vista, I have been one of the unlucky ones to have NON STOP problems with it. I even gave it another chance with my new rig, to have the same problems over and over. So I have totally given up on Vista, full stop. XP, at the moment, is the most relaible, compatible, fast OS to use for me. I have given Vista plenty of chances to prove itself to me, just to be disapointed EVERY time. So I will now wait to see what W7 brings.
