Clearly, you don't need to be an asshole to be successful. But do you have to be near one?
When Jobs was right there next to him, his body 8% anus by mass, being asshole enough for ten ordinary men, how do we know whether Woz's success was due in part to Jobs' abrasive personality, or in spite of it? Didn't Jobs pull some dirty business tricks to cheat Woz out of some of his ownership?
