I was irate when I tried to run windows after my update. I cant imagine how it is legal to pull such crap on customers. This is the first time since I have been a MAC guy (7 years now) that I was disgusted with Apple. But at the same time, i dont know how Parallels could force customers to pay 50.00 for the upgrade. The whole situation stinks as i just purchased 3.0 not even a year ago. anway- http://toni.uebernickel.info/apple/parallels-3-on-snow-leopard/ this shows how to run Parallels 3.0 on Snow Leopard. Run at your own risk. You have to jump through hoops a bit, but it is simple after you do it once. And running the terminal location to the desk top doesnt seem to work. (crashed my macbook this way 2x's) hope parallels gets to the bottom of this so that we dont have to do this.
