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.
