"I'm a PC and I eat crayons."

You know, these counter-ads by Microsoft seemed misguided in the first place, but the latest one, where the dude intones in a stiff monotone that "I'm a PC and I eat pancakes" seems to be implying that PC users are literally mentally disabled. This doesn't really strike me as a winning strategy--but then, I don't have a multi-billion-dollar advertising department, so what do I know?
