$10 for a diet-coke. I noticed that all right. The cheese-burger wasn't the cheapest burger in the world either :) I thought the exchange at the end was nice. I really like this side of Bill Gates, kind of self-deprecating. His TED Talk where he let mosquitoes out into the auditorium and half-joked that he was pretty sure they weren't malaria carrying ones was an eye-opener as well. This article didn't tell me much that was new but I was surprised to learn about how much he worked and little he vacationed at the start of Microsoft. Credit where it is due.
