Parallels today released a new version (RC3) to its' desktop software for Macs. Parallels Desktop RC3 allows Mac users to run different operating systems on their Intel based machines, without the need to reboot like Apple's Bootcamp. This new release adds support for the new Microsoft Windows Vista, as well as many other improvements. There is also a new look and feel, keyboard re-mapping, and USB 2.0 support. I personally use Parallels and although I do not delve into the Windows environment very often on my Mac, when I do it works very well.
