Im sorry if i affended anyone, I wasent trying to I was just stating what I had heard from all my coworkers, Also my mother was going to buy a computer from dell that said it was vista compatable so I told her what I heard, so she called up dell and asked them they told her when vista came out she would have to upgrade her hard drive for an extra $150 bucks to run it. So from the horses mouth. why dont you call microsoft and ask...dont be so cockey we all can be wrong from time to time and technology changes...All with love to my fellow computer nerds=-)
