thats kinda true. (even excluding gemini lynx user like myself) comps and phones have reached overkill for most users. therefore sff is totally fine for most users.
truth is.. only reason i dont have a bigger pc is that i want flexibility to move apt if my landlord raises rent. thats literally the only reason.
otherwise i would have dual socket, 8 sticks memory, full sized gpu, etc.
i dont mind not having all that. although, it could be used for something.. currently it would be used for nothing.
