Any time Jobs had to step aside from the CEO position temporarily, Cook took over immediately. Metaphorically speaking, Cook kept the trains running on time. Cook did not set or change the direction of the company at the time, and Jobs was still available for consultation.

> He was Jobs' designated successor for a decade when he learned he was sick.

> Jobs loved Cook.

In what way? According to biographer Walter Isaacson, Jobs lamented that Cook was "not a product person".
