I 100% agree. I'm basically finished the book (2 more chapters to go, but I skipped ahead to the last 2 chapters out of boredom). It reads like 2 different books: before coming back to Apple the second time, and after.
The first half really makes him look like an utter wretch, and almost suggests that his success was a mistake. It basically talks about what an asshole Jobs was, and how he would yell at everyone, etc, and it wouldn't talk about what actually made him a success in his early years. There was almost nothing on it, just anecdotes from people about how he smelled, he was rude, he cried all the time, and made people hate him. I would have loved a more balanced approach to hearing about how he was able to bring the Macintosh team together through inspiration. It basically felt like "Jobs was able to get the Macintosh team together by manipulating and exploiting them with his reality distortion field." I didn't find it very good at all. I also would have liked to have read more about NeXT and what problems he had besides overspending, etc. Were there successes?
The second half of the book was more interesting, because it stopped ragging on Jobs being an asshole and talked more about what he did. There were far more anecdotes, I guess maybe because he interviewed more people from this era. But at least I got a sense of what he actually did for Apple, vs feeling like he was more lucky than good.
Overall, I think the biography stunk. It's useful in that he did get access to Jobs in the final months, and getting insight into his illness, etc, was interesting and sad, but still overall I think he did a very poor job, especially about the early years.
