I think Jobs had a point about designs that require a stylus. There were many portable computers before the iPhone that required a stylus. iOS was designed with fingers in mind and then added a stylus for some kinds of work. This is similar to how the original Macintosh had no arrow keys and forced developers to design for the mouse. Later designs then added arrow keys.
