O NYTimes traçou o Perfil do Tim Cook. É uma boa leitura.
Melhor ainda a parte em que é confirmado o iWatch.
É citado o desenvolvimento do chamado iWatch e que Tim Cook não se envolve nos detalhes de engenharia do projeto.
They point to the development of the so-called iWatch — the “smartwatch” that Apple observers are eagerly awaiting as the next world-beating gadget. Mr. Cook is less involved in the minutiae of product engineering for the watch, and has instead delegated those duties to members of his executive cabinet, including Mr. Ive, according to people involved in the project, who spoke on condition of anonymity because they were not authorized to speak to press.

Definitivamente vale ler esse Perfil do Tim Cook.
