The Apple Watch was the last product Steve Jobs envisioned and planned. You can't put that on Tim Cook.
And right now they are being more number centric rather than innovation centric as in the past years.
No evidence Steve Jobs was involved in the planning/design of the Apple Watch. In fact during the Wired interview with Ive:
“Ive began dreaming about an Apple watch just after CEO Steve Jobs’ death in October 2011. He soon brought the idea to Dye and a small group of others in the design studio.”
And plenty of innovations for me: A12X/T2/W1 SOCs, FaceID, Apple Watch ECG, HomePod spatial detection, Beats1 Radio, Handoff/Continuity, Apple Pay.
Also under Tim Cook’s reign Apple has dominated the wearables market with a product that everybody dismissed in the beginning.
