Bill Gates has announced that he's stepping down from his day-to-day roll as CTO at Microsoft so that he can focus full time on this philanthropic foundation. Last week at his keynote at the Consumer Electronics Show (CES) 2008, he showed a video of what that day will be like. It's pretty funny.
YouTube has a recording from the audience.
There's a better recording at Bill Gates Last Day At Microsoft: The Movie.
The official recording of the entire keynote, including the video, is on Microsoft's site under "Live Webcast: 2008 Microsoft CES Keynote".
