A few days ago at work, I had a co-worker giving a demo on his brand spankin' new VAIO laptop of how to install and set up a wireless lab monitoring system that we just started selling. He got to the program's setup window and the screen went black, wouldn't recover, holding power didn't even turn the thing off, had to pull the battery and do a hard reset. Restarted, got back to where he was, BSOD, reboot, BSOD again. So I grab my Macbook, boot into XP, plug in the USB cable of the receiver, pop in the install disc, and have it running in minutes so he can continue his demo for everyone.
Just another example that showing how Macs are PCs too and can run windows when they need to goes a long way.
