As I get around and talk to geeks I would tell them that I’ve been using Parallels so that I could run Windows on top of my Macintosh’s OSX operating system, but have had some troubles with crashing and other things. The answer back has been quite consistent: that I should use VMWare’s Fusion.
So, I finally gave in. And, damn, it is nicer and faster. You can even drag VM’s from operating system to operating system (very useful if, for instance, you’re a software developer and need to test stuff out on many different OS’s and then you want to move those OS’s around to other machines).
By the way, these things let you run OSX and Windows together. If you’re scared of moving to the Mac, this should finish that argument off.
