I'll second the MacBook Pro. I run in both Boot Camp and Parallels running the BootCamp partition. I like being able to run any Mac or PC software I like. Plus, since Mac's are very particular about HDCP, a Mac laptop makes a great test signal generator. I have been called out to several jobs where someone eventually (weeks or months later) brought a Mac to plug into a conference system at it would not work due to HDCP.
