seriously the comments here make it sounds like he was a Thomas Edison single handed inventing the iPod and the iPhone, he is not, he's closer to an artistic director/business strategist, he gave apple a direction and a goal, it was the engineers that worked their butts off to make a working product that closely matched Mr Job's expectations, he did not come up with all those apple patents himself, it was an engineer who worked for apple that came up with those ideas
what he does have though is exceptional business acumen, he was able to capitalize on market opportunities and i have to admit smart enough to realize that creating an ecosystem around a product creates addition revenue streams and extends the product's appeal and increase the likelihood of future resales through platform dependencies and product obsolescence, and that's why apple shares get rocked so easily, there is no one else in apple with that kind of business acumen
