Microsoft Virtual PC for Mac 7.0 with Windows XP Professional review:1 stars (Lack Of Resources) - The problem with this software is video streaming and games. Almost all games and video need a minimum of 32Mb for video. The max this software can do is 16Mb. So, if you are using this jsut for office applications than this is the software for you. If your trying to use games and stream video for surveillance purposes from a pc based dvr with a remote access software it is impossible because you need the 32Mb of video minimum.4 stars (good but slow on certain tasks) - It is a good product I have not had to put it through all of its paces. Having written that I did see poor performance on websites that are heavy in games. My youngest was on [...]and the game was slow in comparasion to OS X.3 stars (It's just OK) - I had to purchase Virtual PC for my Mac because of software needs in a statistics class I'm taking. I tried to avoid this purchase as long as I could. Now that it has been installed (it took 3 install efforts) I find it to be slow and clumsy. It is now a part of my computer out of need - not desire. So far it is doing what it is supposed to do, but in the typical Windows non-intuitive manner with a lot of excuses and expectations that are not seen with the Mac OS. I guess it's OK, but I'm not a big fan of having it on my computer. I feel contaminated. If you need this software, it will do the job but no where near as well as what we have grown to appreciate with a Mac.
