I've been using a MacBook Pro for the last year for everything, except for Pic projects. I use a program called VMWare Fusion to run WindowsXP, and it works great. A Mac can boot into Windows using Apple's Bootcamp, but you have to reboot the machine to change operating systems. With Fusion, you just start it like any other program, and move the mouse into or out of the program. Fusion also will run Linux on an Apple.
