Innovative design doesn't work without an internal champion who can rally the company around unconventional ideas. Jobs played that role, but now Apple is led by the operations team. The word "design" does not appear anywhere on their executive leadership page.

Unconventional ideas are inherently risky. They're just not worth pursuing if buy-in can't be secured and leadership is more focused on compromising to increase profit margins, etc. For that reason, it's great (in the short term!) that Apple is rehashing known-good designs from a decade ago. However, I don't see that strategy working in the long term.
