Something I really dislike about the way he presents his work is that he is intentionally really really vague about what his contribution was to those various products, in his presentations he often shows a few slides "I worked on this, this and this", where the iPad and watch get shown..

Like, what did you do? Design the home screen? Design the vision of the machine itself? It's ambiguity taken to its highest extreme.

I really respect his work and publications though, no doubt that he made important contributions to the products he shows on his slides.
