I just read the book "Accidental Empires" by Robert X. Cringely that was the basis for the PBS movie, "Triumph of the Nerds." The book deals primarily with the early personalities who were instrumental to the success of Apple and Microsoft. It is very liberally sprinkled with Cringely's ideas of why the major players were successful as well as the mistakes they made. I found it a bit disappointing in that very little mention is made of CP/M, its history, or the associated people, companies, and machines. However a lot of Apple and Microsoft history gets included and I found the anecdotes to be most interesting! I wouldn't call it a "must read" but rather something that gives one authors perspective on the happenings and sometimes behind the scenes events that created this industry.
