The book by Leander Kahney is interesting as it shows how Steve Jobs is unique in the high-tech world. Let me just mention a single example: “But unlike a lot of people in product marketing those days who would go out and do customer testing, asking people what they wanted, Steve didn’t believe in that. He said ‘How can I possibly ask someone what a graphics-based computer ought to be when they have no idea what a graphics-based computer is? No one has ever seen one before’.” …and… “Like Henry Ford once said: ‘If I’d asked my customers what they wanted, they’d have said a faster horse’. ” (pages 63-64).
If you like this, you’ll enjoy the book. Thanks to Jacques for recommending it.
