There's a lot of judgements being passed here on this forum and that's not cool. We don't really know the dynamics of these relationships, and until we read Lisa's book, we don't really have any insight. Also, the dynamics between Lisa and Steve are saddled with tons of drama that Steve and her mother created--we don't really know the pre-Lisa story.
Jumping to conclusions with global comments, "Steve was an ass... jerk... dick... whatever" and having that affect your relationships with Apple or the products is a bit asinine because Steve's personal relationships should have nothing to do with how you view Apple's products. If everyone thought like that, nobody would've ever bought a Ford because it's said Henry, and his son especially, were complete jerks. Many levels beyond Steve.
Often celebrities are saddled with some personal issues, drama, psychological problems. Steve was adopted by parents who gave him up. Then with the efforts of Woz, they created the most successful company ever. He was the youngest instant millionaire to be at the helm of a company going public when Apple went public and he was placed on the cover of Time magazine! Was he, what, 24 then? That's akin to instant stardom that celebrities deal with and for a lot of people, it's hard to mentally manage--especially in your early twenties. Wouldn't you agree?
I'm not saying whatever dickish things he did was ok because those things were not ok. Yet later, we find Steve learned how to manage a company, learned how to be a great family man, and left an incredible legacy. Also, I know people who had dealt with him personally in business and none of them call him an ******. He was tough, yes, but not universally a jerk.
I do want to read Lisa's story because it's fascinating, important, and helps us all understand the complex mind of Steve Jobs. Her story won't change my belief in his business acumen or the amazing legacy he's left behind, however.
