I replaced my dying gaming laptop with a steam deck about a year ago now. At home I have it set up in a dock, connected to a good monitor with keyboard and mouse.

It does everything I want it to except, and I just found this out this week when trying to make some proxy cards so my kid can play Lorcana, that Arch Linux apparently doesn't support Brother printer drivers currently. Something about not having CUPS? I don't know but I'm a total Linux layman.
