I don't mean to be petty but it's not "economics" that drives prices down but rather competition. The thing about smartphones is while they all had dramatically different surface behavior, underneath they all shared very similar technological cores (Qualcomm processors, iOS/Android/Windows OS, etc...) and were able to utilize those same innovations.

They have been selling it for a long time now, it's not like this stuff is brand new. My only point was that we have not seen the effects you are describing happening yet which is worrisome. It feels like they are happy with product positioning at the moment.
