Jobs was only as good as the people around him, and I feel anyone thinking he was the only bright mind at Apple is insane. Personally I give more credit to Jonathan Ive than Jobs as far as the fanboy/design cachet they now have. While this started with the first iMac that came out after Jobs came back, it really took off after the iPod (all of which Ive designed). Jobs always surrounded himself with bright people.
Going back to day one, Apple would not have been a speck on the radar, and much of where they are now goes back to the 70's when it was essentially just Jobs manning the press, smoke and mirrors, and Woz having a good (and playful) mind for hardware. Not to mention good timing and a great amount of luck. Who would have ever thought Jobs old desires to knock IBM out of the consumer computer marketplace would essentially come true, looking back to the 70's?
Jobs may have been the guy to put the seal of approval on products but I honestly don't think he had as much of a vision in the concept of said products as people give him credit for. He was a hell of a showman, but I think the stories of the current breed of Apple products coming to him in a dream and him doing them solo from start to finish are extremely far from the truth.
Either way, it worked. Even those that dislike Apple products can appreciate the usability and design aspects of what they sell to some degree. The dude was a shrewd and sometimes cruel businessman, but you can't argue with his results even if you do not respect his methods (which I do not).
