As far as I'm concerned, I am NOT impressed with this product. Yes, it's "neat" to see Windows or other operating systems running simultaneously with Mac OS X, but that all depends on one's definition of "running". First of all, I can't even plug in a simple USB device. I have to use networking just to get files from the mac side of my computer to the windows side. I can do anything on my mac that I want except play specific games. Friends of mine send me links to WINDOWS games that, for some reason, will not run on Parallels. I used to have boot camp installed on my computer, and the games at least ran on that. Which was a beta. That I did not pay for. This product has waaaaaay too many bugs and errors and I'm not going to go looking around for the patch and update for every little thing that goes wrong. I really hope a new version of this is released soon, minus the hassle.
