Smith Micro now has a program called WMware Fusion that's supposed to make your Mac experience bearable by being able to run Windows based apps on your Mac without rebooting.  It's on special offer at the moment:

WmWare Fusion.

I don't get the whole "finally on a mac" thing though.  My PC was replaced with Mac in my work place some years ago and I was told it would change my whole computing experience.  It didn't.  Wasn't much worse but it didn't offer any improvements to my PC.  In fact, even companies like Adobe have features in their programs that are "PC only".
