Parallels, the virtualization software that runs Windows or any other OS like Linux at the same time with Mac OS X is a pretty cool piece of software. But, it just got a lot cooler with the new Release candidate that can also run  Windows Vista simultaneously with  Mac OS X.

 

So, if you have an Intel based Mac and  want to give Vista a test run without risking your data  just get a copy of Parallels. See, this is why we love our Macs.
