Apparently money can't buy a sense of humor. In a recent interview with AdAge, Bob Garfield asked Bill Gates about his thoughts on the John Hodgman "I'm a PC" character from the Apple ads.
Of course, no matter how hard they try, they'll never be as cool as John Hodge-man. (Which is why the original Apple ads ultimately fail: Hodge-man is more desirable than the Mac twerp. John's a hug from a tweed library.)
