What this chart is missing is the impact of the quality of the screen and the source material being played on it.
A shit screen is a shit screen, just like a badly filmed TV show from the 80s will look like crap on anything other than an old CRT.
People buying a 4k screen from Wallmart for $200 then wondering why they cant tell its any better than their old 1080p screen.
The problem with pushing up resolution is the cost to get a good set right now is so much its a niche within a niche of people who actually want it. Even a good 4k set with proper HDR support and big enough to make a different is expensive. Even when 8k moves away from early adopter markups its still going to be expensive, especially when compared to the tat you can by at the supermarket.
I would buy a feature phone today, preferably something eink, if it was painless to switch my SIM between it and my smart phone. Having to take the SIM out of one, put it in the other, then turn on the phone is not painless and they do not design the little draws to support thousands of open/closes against the contacts to read the SIM.
There are times I want the smart phone to have the SIM because I will want or need the extra functionality and if you just make the feature phone do everything then its just morphed into a smart phone with extra steps. I want the feature phone to be basic as I can get away with.
That said, I really want google wallet or similar that I can share between the two phones for my passes and tickets, audio streaming support, and maps. Something like a Hisense A9 would fit the bill but the temptation to add more apps than the basics would be too great, plus I still need a way to switch SIMs between the phones.
I cannot replace my smart phone, rather than supplement, with any feature phone because I use it for such a wide range of things. I can ssh from it to my home devices, I can manage my bank accounts, it tracks my health, it provides video and audio streaming on and offline, I can read and write documents/spreadsheets, plus anything you can do via a web browser.
