Walter Isaacson's biography of Steve Jobs is the only official version of Jobs's life. The book has received critical acclaim. It is a story of a designer-at-heart who ignored convention and created some very elegant devices - it is a story that architects and designers aspire to. This is a great book for any designer who has an affection for Apple products, which are often considered some of the best designed electronics available.
The book is also available on the Kindle (we aren't sure how Steve would feel about that).
