I've found the recent U.S. TV ads of Groovy Mac Guy and Staid PC Suit Guy to be pretty annoying, especially considering the recent discussions by Mac people of how appealing Ubuntu has been looking to them (Dave Megginson, Tim Bray, and others they point to). It would be nice to add a Linux guy (who, to be honest, would probably look a lot like Comic Book Guy) discussing with the PC guy how much open source software they had in common, but I suppose Mac guy would then say that with OS X, they're catching up there—not in so many words, of course.

Anyway, YouTube has some hilarious parodies of the Mac ads.
