Why You Should Buy a Mac (?)

Apple’s marketing department sends me email once every week or so.. Today they’re trying to persuade me to swap my PC for a Mac:
“Frustrated with your PC? Time for a Mac.”
Ok. Convince me!
The Apple marketing department aren’t that bright… or maybe they’re on a different wavelength to the rest of us:

Ok. The guy on the left looks a bit boring, but the guy on the right looks like he’s missing a few brain cells.
So would buying a Mac result in a loss of IQ?
