Hmm don't think I buy this, at least in Apple's case.

They have a monopoly on the operating system, which is what people really want with both the iPhone and the Mac.

People will still spend $3000 on a 15" MacBook Pro that they hate (because of the ridiculous touchbar) because it's the only high spec'd laptop available with macOS.

There's no way for consumers to tell Apple "we prefer no touchbar" purely with sales data because they aren't given the choice.

I think that same factor is huge with the iPhone. I have bought multiple 4.7" iPhones now, all of which I hate because of the size, but it is the smallest (correction: smallest premium) phone Apple makes/made. So looking at the data, it looks like I love the new iPhone size because I bought it, but the reality is I had no choice if I wanted to keep using iOS and didn't want to deal with a horrible experience performance-wise from aging hardware.

Apple's a special case, but we're not seeing the various Android vendors (nor the cellular carriers) giving any appreciable retail space to small devices either.

They're largely relegated to Walmart's "I need a cheap burner phone" prepaid phone department.
