Last night I installed Sun Virtual Box. I installed Open Suse Linux on it. It works very well I have virtual box on Vista, and Suse works great on it. It only takes a couple of minutes to switch from Vista to Suse. You can also install on it win98, winme, winnt4, win2000 and winxp. Also some other Linux versions are Ubuntu, Fedora and Redhat. I like this very well they use it at the community college I go to and the best thing is the software is free. Oh and they are making it so you will be able to install Mac software. Just google Sun Virtual Box download.
