That's the book that uncritically repeats Jobs' (completely bogus) claim that Apple invented the switching power supply.

To me it actually had the opposite effect: after reading it I had a newfound respect towards Apple and Jobs. The book was honest and fair, I don't know why people think it does a disservice to him since everyone knew he was an asshole. This is coming from someone that avoids Apple products, FWIW.
