A lot of linux native software example redshift still does not work on the rpi. Lot of things are broken. Recently i tried to use it as a basic desktop replacement until my new laptop arrives. Does a terrible f job.
A 10 year old celeron n2930 based mini pc i purchased for 30$ at a scrapper performs way better than the pi4. Ran esxi and bunch of vms on top of it aswell. Sips 10 w of power.
I used my RP5 as my main machine for the better part of a month. It worked surprisingly well, even with just an SD card.
I tend to prefer small x86 boxes myself but the discussion here was supposed regressions on the Pi 5's ability to run anything but the official OS, not general dislikes. Similarly, I think the Redshift thing is actually an X11/Wayland debate.
