I wasn't being 100% direct either. The author still credited, or better yet, blamed Jobs for something he didn't actually do-- design the iPad. It seems pretty common, at least with non-techheads, that "Steve Jobs" is used interchangeably with "Apple".
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.
