Run Windows 7 in a window on Mac OS X

"I’m using a Macbook Pro laptop running OS X and I have Windows 7 installed on the Bootcamp partition. Normally this kind of setup only lets you boot up either Mac OS X or Windows, but with VMware Fusion 3 for Mac OS X I can run the bootcamp partition (Windows 7) as a virtualized guest operating system. The Unity feature of VMware Fusion lets Windows apps appear in their own window on the Mac OS X desktop. That always turns heads because people say, “You’re running Outlook on a Mac?”."
