Parallels Desktop for Mac lets you run Windows (and other OSes) on your Intel Mac. I’ve had it for a few days, but one of my coworkers showed me the “Parallels Tools” today. Wow. Make sure you install the tools when you use Parallels with Windows. It’s so cool. The mouse seamlessly moves between Mac OS and Windows as the cursor goes over the Windows window. And, full screen mode looks right now (before I had black bars on both sides of my MacBook Pro’s widescreen display). I haven’t tried to VMware beta on the Mac, but I can say that Parallels at least is most excellent.
