Bill Gates, we'll miss you. Not just because you're the ultimate geek-villain-pioneer-entrepreneur-monopolist. But because you've always been there for us. To love. To hate. To envy. To pick on. So this month, your last as a full-time Microsoft employee, we realized it was only right and proper to look back on your storied career. (Or we just love your mug shot from the Albuquerque arrest.)

1950s

Gates and Lakeside classmate Paul Allen learn Basic from a manual. Within a few weeks, the pair exhaust the school's $3,000 annual budget for time on a PDP-10 computer. The boys soon land a contract with the Computer Center Corporation to report PDP-10 software bugs in exchange for computer time.

1971

Gates writes programs for Lakeside, including one that creates class schedules; he manages to put himself in classes with the "right" girls.

Gates enrolls at Harvard University. Academically, his record is spotty — having a near-photographic memory helps him cram, but he often misses class, neglecting showers and living on pizza and soda while programming and playing poker. He befriends Steve Ballmer, who lives down the hall in the same dormitory.

January 1975

Paul Allen sees the cover of Popular Electronics — a picture of the Altair 8800 computer and the headline "World's First Minicomputer Kit to Rival Commercial Models".
