Earlier quoted context omitted.
Because I want a great camera in my pocket. It’s only a few dollars more a month.
There will always be people who want the best, but good enough solution serves most people. Smart phones have reached a point where most are at least good enough. A flagship Samsung is say $700. That is $500 more which is more than a couple bucks a month. Clearly well worth for you but probably not for a good portion of society.
If you’re talking about global markets then of course, $200 phones have always been more common. That’s why Android has 80% market share.
