Yeah, Apple is doing really well, but I think from the profits point of view, their profits could have been even higher if the iPhone X 64gb was priced around $800-850. I see it as an "experiment", how much are people willing to pay for a new iPhone. And I think they kind of succeeded, but from my experience, I know really really just a few people (I mean like 10-15) that bought the X. I'm a developer, so I'm surrounded by tech people. And almost everybody who has and I have been talking about the phone said that it's a nice phone, but not worth the money.
So I kind of agree with you, but I think there is much you can improve. Those things that are not getting so much attention like battery life & durability. Maybe we got to the point where the phones are great in almost every aspect except those. I don't know, but knowing Apple, the shrinking market will result in unrepairable a quite fragile phones.
