Who many backgrounds of his time at Apple wants is certainly etnntäuscht, but Woz tells about his childhood, his affinity for technology, the development of the Apple I and II and what he has driven to his tenure at Apple so. The whole on a very open, perhaps somewhat naive way. At one point or another in great detail (especially when it comes to technology), but sometimes a few years are simply times skipped, until the next, in his opinion, interesting story. Certainly not for everyone, I found it funny.
The style of the book, which is in many other reviews called bad, makes the book in my opinion, just interesting: you feel Steve Wozniak sits one opposite the beer and chatting just so it happening, added in very "casual" everyday language , I find personally compared to other autobiographies, for example, a Gina Wild who tries to speak German properly, more authentic.
Also, I have not felt as unsymphatisch Woz in his, by German standards, very self-representational art. But Americans hold simply not so vibrant here if you think to have done something good. This starts with good school performance and goes just screwing together the first PCs with keyboard and TV connection on. As the Americans like to knock on the shoulder where you certainly would be a little more restrained in Germany, just cultural differences.
In short, he does not put on, but you get a very good impression as man Steve Wozniak is (as far as one can deduce from a book) and that is indeed the point of a biography.
