As a fellow long timer, I'd say the perception of actual value (ecosystem and products) has decreased under Cook.
I think you're looking at it through the wrong lens. If you're all-in on Apple, everything works very nicely together, much better than any other set of products out there. When you're that far ahead of everyone else, it's frankly easier for others to catch up than for you to stay ahead. Big leaps don't happen very often. In the interim, your competition starts to catch up.
If anything I think Cook has done a great job of maintaining the value perception in the face of ever-increasing competition. There's no argument that other products are getting better and better. Despite that, Apple has maintained it's dominance in the mobile phone market. The top selling phones are still always iPhones. How can you argue that the perception of value has decreased under Cook when the market clearly disagrees? If that perception had decreased, people wouldn't continue to pay top dollar for Apple products and Apple's devices wouldn't consistently be top sellers in their respective categories.
Other options are getting better, but that doesn't negate Apple's value perception and I think Cook has done a great job of preserving the perceived value of Apple's hardware and ecosystem despite the competition making significant improvements.
Things like not having ProMotion everywhere by now are an example of Tim's style vs Steve's
Steve's style was somewhat utilitarian and it was just what Apple needed when he returned. But would that be the right path in today's world? In Steve's world, we probably would have just one iPhone. There'd be no SE, no Pro, no different screen sizes, no differentiating features. Would that approach have taken Apple to where it is today? I don't think so.
Yes, under Cook, there are differentiating hardware features and certain ones cost a premium. If every device had ProMotion every device would cost a lot more. Eventually every device will, just not today.
Steve was VERY much about getting the best products out there and upgraded to what is "best for the product" once it was feasible. Tim sees those same situations as price tier creation opportunities instead.
Steve didn't see the need for a big product mix. He thought everyone should pretty much have the same device. Would that work today? And why is that approach better than Cook's? In Steve's world, "best for the product" also meant the product was destined to be very expensive. Cook's approach makes Apple products more accessible.
It's just the difference between a Product person and a Financial leader like Tim is.
Not at all. It's Apple's diverse product mix that has made Apple successful. Under Cook Apple started giving customers a lot more options and guess what happened? They grew into a multi-trillion dollar company. Honestly I have no idea what you're complaining about. Cook is clearly much more of a product guy because under his leadership Apple has sold A LOT MORE products!
