Today the first beta of VirtualBox has been released. It is actually the third product that hits the Mac market after the successful Parallels and the still-in-beta VMWare Fusion. Still havent tried it that much, so I cannot comment on performances or features, but it is worth to note that it is open source and free for personal use. Check it out here: http://www.virtualbox.org.
