I am very surprised how little Apple stock Steve Jobs has. Most of Jobs worth is actually in Disney stock (obtained from the sale of Pixar). Considering that he does not take a salary either, Apple are getting a pretty good deal on a CEO from him.
He could've had much more. He sacrificed 15 million options for something like half that in actual shares, because he didn't think the company was going to do well. When he was ousted from the company, he sold all those shares. If he held on to them, he'd be much wealthier.
