Programmers At Work, 22 Years Later
Firebones writes "In 1986, the book Programmers at Work presented interviews with 19 programmers and software designers from the early days of personal computing including Charles Simonyi, Andy Hertzfeld, Ray Ozzie, Bill Gates, and Pac Man programmer Toru Iwatani. Leonard Richardson tracked down these pioneers and has compiled a nice summary of where they are now, 22 years later."
If you like reading about the earlier days of personal computing, I'd also recommend Fire in the Valley by Freiburger and Swine which has a ton of cool anecdotes and dramatic confrontations.
