First things first: Steve Jobs was a bit of a prick.
I've read several books on the man, and however much of a visionary or perfectionist or whatever he may have been, he was also a selfish ass. An ass with some looney ideas.
That said, he was very good at making you believe that he had the answers, and pushing his people to excel beyond what anyone believed was possible.
This book does not put Jobs on a pedestal, nor does it vilify him. He was a human who made mistakes, like any man. This is the life of that man.
It is very much worth the read.
