I wouldn't say Jobs was that important of a historical figure. He, at the end of the day, was a business man and good at marketing. I would find a biography of Wozniak more interesting since he actually did a lot of the early engineering at Apple and was the technical genius in the early days of Apple.

Essentially, I think Woz would have gone on to make a name for himself with or without Jobs. Jobs on the other hand, probably would have been a nobody without Woz.
