There's a new biography of Steve Jobs, Becoming Steve Jobs (iBooks) (Amazon), by Brent Schlender and Rick Tetzeli. I've already bought it and am looking forward to digging in. The Walter Isaacson Steve Jobs biography, released shortly after Steve's death, felt one-dimensional to me. It seemed to catalog his sins more than explore why he was so influential.
I fully appreciate that Steve Jobs had his flaws. What makes him interesting is how successful he was despite them. If we truly was that tyrannical, how could he possibly succeed? Early reviews indicate that this new book does a better job of answering that question.
If you are on the fence about the book, read this article by Steven Levy, which is what convinced me to buy the book.
