Parallels Desktop 4.0 Available

"Already the world’s No. 1 selling Mac system utility, Parallels Desktop for Mac now has more than 1.5 million users worldwide and counting. Parallels Desktop 4.0 for Mac provides the complete suite of essentials to run Windows on the Mac the easy, fast and powerful way."

The one thing that has always annoyed me about Parallels is how greedy it is when you run it and the lack of performance you get when accessing the file system.  According to Ars, they've made big strides in the performance area (50% is a nice number) but as with all benchmarks, I'll have to see that one to believe it.  I'm probably going to spring for this upgrade, though.  As little as I actually use Parallels, it's very handy to have around.  Any of you folks out there have it yet?  If so what do you think?
