About two hours ago, I received my copy of Inside Steve's Brain, which is now in stores. I've had a chance to skim through the book quickly, and so I've gotten a brief idea of the book's content and tone.
As expected, Inside Steve's Brain deals mostly with Steve Jobs' career and success at Apple. The sections on his work as a co-founder of Pixar are rather light on new information, and consist mostly of anecdotes already known to most Pixar fans. There are a few vintage quotes from Jobs regarding Pixar, which I hadn't read before, that I enjoyed.
Really, the book is not even so much about Apple as it is about Jobs himself. It's more about his personally and management style. And his quirks, of course.
For example: At one point in his life, before starting Apple, Jobs went on an all-apple diet, hoping it would prevent him from having to shower. To quote Kahney: "It didn't." (This was apparently during his LSD experimentation period.) Even now, Jobs often insists on walking barefoot to the local supermarket to pick up a smoothie.
All this paints a really vivid picture of Jobs, who Wired magazine recently termed an "evil genius".
This book is comprised of either 80% stuff you didn't know, or 80% stuff you already knew, depending on your familiarity with Jobs, Apple, and Pixar.
Either way, it makes for an interesting read. And very entertaining.
