Seinfeld the Microsoft pitchman

Does anyone find it somewhat funny that Jerry Seinfeld signed on as a pitchman for Microsoft to do battle against Apple?

Didn't Jerry have an Apple Mac in his apartment for the entire run of his show? And wasn't that Mac updated every season with the newest model? From what I've read, Jerry had such a firm control over that show that he was involved with every minute detail. His love of Superman and racing is evident... he had the caped hero and a Skip Barber Racing School magnet on his fridge, so I have to assume he was a Mac user too.

I'd love to say "not that there's anything wrong with it" here, but I can't. Seems like a bit of a sellout.
