Things he effectively presided over:
* Apple Silicon, the most far-reaching technical transformation in the company's history (probably a bigger deal than macOS itself)
* Apple Pay
* The Watch and Airpods product categories, both of which Apple now dominates.
All while holding on to its position in phones and improving (drastically) its computers.
It feels like a pretty successful term.
Tim was a great CEO.
I'm just pointing out product velocity slowed. I'm far from the first person to say it, it's just a fact. In the five years before Cook we got first generation Apple TV, iPhone, iPad, and MacBook Air. Your list spans 14 years.
Also the discipline in not blowing massive R&D chasing AI; but having the machines/architecture best suited to said AI...
Yes, a very successful CEO and he secured a great legacy. I was skeptical when Jobs stepped down, but under Cook innovation did continue, but primarily in hardware.
