On the other hand, it seems pretty common for techheads to misunderstand what "design" is. I'd say Steve Jobs designed the iPad the same way Frank Gehry designs his buildings: by conceptualizing it and sketching the overall design, leaving the details to his aides.
What was the "design" then? A sketch of a really thin tablet PC? That doesn't seem so creative or innovative to me. I think more credit is due to the engineers who brought it to life. Moreover, I haven't actually seen any sketches done by Jobs. I'm not saying they don't exist; I just haven't seen any.
