VMware Fusion vs. Parallels?

[steveza]

I might need to run program using either linux or unix,.... which one will better support them?

I use VMware for this on both Windows and OS X.

I had paralles 3 for school, it pretty much sucked. I got fed up contacting the parallels technicians and upgraded to 4.0, it works wayyyyyyy better. I havnt had a crash yet, my blackberry manager works on it now via usb, games work, and there is more options for configuring your system as well. But i do believe fusion is cheaper
