Lauda89 There definately are things in hardware to watch out for but thankfully these issues are now in the public eye, that's why we can buy PWM-free/low blue light displays.
In my own situation there have been so many 'upgrades' that have bricked my usuable devices into unusable, or certainly more uncomfortable than before.
I would say that it's not getting too complicated, if anything taking hardware out of the equation simplifies things. It also means that a software fix would solve our problems overnight. Therein lies the frustration, it can probably all be fixed with a few lines of code, but it is a walled garden.
