Interesting, but one issue with the monoculture of Android devices that impacts a non-insignificant amount of people is the fact 'top-tier' devices such as the Google Pixels that have reliable firmware support or security also have OLED displays with aggressive PWM flickering. That makes these devices a non-starter for many people with headache or some seizure disorders.

I really wish Google and other OEMs would do something about this at some point.
