That's like saying "nobody wants lights in the car boot because if they wanted it the demand was there and market would provide" I hate that dumbass argument.

That's like saying "nobody wants lights in the car boot because if they wanted it the demand was there and market would provide" I hate that dumbass argument. Every fucking time someone brings it. Nobody fucking buys thing like a smartphone or a car based on a single feature while ignoring every other feature. You buy a thing. There is like half a dozen to a dozen different factors. Battery life, screen size, CPU, RAM, storage etc. If there is no phone with the "niche" option like replaceable battery that ALSO have all of the other features in acceptable range, people will not buy it. It's NOT because they don't want <niche feature> It's because picking <niche feature> means bigger compromises in other areas that are also important
