I'm a little less than a third of the way through and find the book quite interesting. It seems to be a fair portrait of Jobs, blemishes and all. I'm writing this before finishing, though, in defense of the narrator, who seems to be taking quite a few hits on this page for, apparently, not sounding enough like Steve Jobs.
Here's my take: The narrator is just fine, and does a clean, professional job, comparable to what you get in many of the best biographies. I've heard "terrible" narrators; this fellow is not one. His reading is nothing that would normally raise complaints. He does not do a Steve Jobs impersonation, which is exactly the way I, personally, would like him to approach it. But Jobs was such a public personality, with a nearly cult-like following, that some listeners seem to be taking their obsession with Jobs out on the narrator because he is not Jobs. I don't think that is reasonable.
So, I'm enjoying the book. I hope you will as well.
This was a well-written and well-read book that did not drag in the least. It will particularly appeal if you enjoy science and experimental design. I think it would be almost as good even if you have other bends. The human side of the story is enjoyable while the significance of the medical breakthrough against Polio is noteworthy. The tie-ins with history events in the US with FDR and other issues in the 30's, 40's, and 50's brought the book home to me.
