vmware player is better, and free, and fast. You can even install everything like Linux as it evevn gives you a virtual hd to use, which is sonthing you can make youself. Virtual PC is way expendsiv, and even Qemu is free ( http://www.oszoo.org/ ) so I find it better to usee a free alternative. Just install any os and run it like it's really there. It's awsome.
