Look at how much R&D spending has gone up over the last years, all while macos and iOS does not become any better and new iPhones are straightforward stepwise improvement on previous years version.
It still feels snappier to play a gameboy or use a windows 95 computer with a CRT screen which is bizarre.
There was this huge push years ago about Retina and resolution because "eye candy sells" but gaming and mobile has been pushing the Hz/Fps game in the last years, and i know the new Apple displays have "Promotion", but still theres tiny click latencies all over the place not to talk about how long it takes many apps to open on "supercomputers".
I wonder if anyone has made comparison from click to screen on a gameboy compared to say a macbook pro.
