Walter Isaacson is a well respected biographer asked specifically by jobs to write the book. I dont have time or the access to corroborate it, but it felt accurate reading it and was in line with other things i've read. Also, some objective facts like screwing over early employees and disowning his daughter make it easier to believe he was capable of pretty bad actions. Bill Gates also grew up a lot and devoted the latter half of his life to helping people, which helped. What parts were wrong?
