Paul Allen is one week older than me. I have more kids but he has more toys -- a LOT more toys -- including professional football and basketball teams, SpaceShipOne, lots of planes and a HUGE boat. Allen is an enthusiast of epic proportions, but one of my fondest images of him was from the 20th anniversary party for the Altair 8800 computer (arguably the first PC), when Paul Allen-the-billionaire wanted some fast food late at night and -- not having a car -- WALKED through the drive-through as part of a long line of cars.
Interesting article on Paul Allen, and Bill Gates' $10/hr position at MIT.
