Actually, thankfully, Virtual PC is just a Microsoft Windows emulator and not actually produced by Microsoft. And it does work very well. Older VPC versions would not play nice with peripherals plugged in via USB or other ports. Now they do. I can use my PC-only MiniDisc software (developed by Sony) on Virtual PC and plug my MD player in via USB and it will all work together well.

Oh, and for those keeping score... that's five Mac aficionados. Three who own and two who are going to buy when the money is made available. Welcome to the "Dark Side" of computing, Jambe.
