A disclaimer: This is not a hagiography, nor is it a sloppy rush job (or, more simply, 'shit!' as Jobs called imperfect work). Isaacson is simply too good a biographer for that. 
 Jobs was clearly a passionate and driven men, and his abrasive and arrogant personality was an extension of that. He honestly did believe in his mantras on art and creating a difference. A contradiction in terms. He wasn't a tinkerer or engineer, as Woz was. He has this obsession for control, power, being an earth-shaking genius. Perhaps he was. But he was still only too human, being highly sensitive and callous in equal measure. 
 Unfortunately, I can imagine too many asshole business school types trying to imitate Jobs' obsessive perfectionist behavior, without his underlying attention for details and vision. 
 Perhaps if it was released a moment later, a little bit on his childhood and his father could have been filled in, but I won't fuss here. This was a very revelatory book, and does a fine job of providing a portrait for his life.
