I've been using Parallels on a Macbook for a year or so. Though I have been thinking of switching to a Windows machine. The guest OS is Win2003 server which runs great. Though I get spinning beach ball problems and need to reboot the host OS fairly often which disrupts my productivity. I may try a Mac desktop next...Maybe it's a dodgy laptop. I've just been on a Mac for a year and enjoying the change of pace but frustrated by the number of problems I've had. It seems comparable to XP on my Thinkpad...but bad compared to my 2003 Server desktop.
