I'm just feeling curious about what exactly it is Jobs does. I know he's the face of the company, but is he involved in the actual design and development of products?
He's the CEO, that is, he makes all the executive decisions. Nothing would get greenlighted, killed off, postponed, moved up, etc without his knwoledge and approval.
He is not directly involved in the design of products most of the time (design is headed by jonathan ives, who jobs seems to trust a great deal), but does offer guidance. I remember s story that he had the idea for the "sunflower" style g4 iMac, but he still wasn't the one who designed it. I get the impression he's more like to be the person who says "not good enough" more than anything else.
