"Peak Apple" is always a good way to tell people your age without telling people your age.
The best way forward is to split Apple into eras:
- Jobs #1.
- Wilderness.
- Jobs #2.
- Cook.
And honestly, I can easily give you Peak Apple for #1, #2, and #3. But I just don't know what it is for #4. I can think of times like the launch of the Apple Watch, but S0 was so flawed and took literally years to become mature. Ditto Apple Vision (if you Google it, the top results mostly involve words like "fail").
I think the Cook era has been... Chequered. A curate's egg. Certainly interesting times.
Profits wise, it's been insane. Product wise... Ah, it's not anywhere near as clear-cut. Arguably, you could say that it was Ive who did much of the heavy lifting. But I suppose kudos to Cook for keeping the boat sailing for so long, and so well. Others could've just sunk it by their arrogance, as in the Wilderness era.
