I bought VMWare Fusion last December to load on my office computer (since our church management software is Windoze only). I've only just gotten around to installing, prompted by WMWare's release of the new beta 2.0. I installed via Bootcamp first, and the first time I saw that "Windows XP" load screen on my beautiful MacBook, I confess I had a little gag reflex. Still, everything worked perfectly... I booted into Windows, played one round of solitaire (which is all I ever see people using Windows for), and then installed Fusion. This application allows me to run Windows apps I must have right alongside my Mac apps.
As I looked down at my dock, I notice that half of my apps are in beta (I can't confirm some, hehe). Here's a screenshot of me running the new beta of Firefox and OpenOffice in Windows on a virtual machine in the new Fusion Beta. (None of which is necessary since both of them run native on OS X now.)
