I have 3 Linux PCs, including a Steam Deck, and 2 out of 3 basically require zero specialized knowledge and just work. One of them has been that way for like a decade and circa every 3 years I just install a new OS to update things and it takes all of like 10 minutes. Steam Deck takes care of itself so far. Leaving the one PITA early model Ryzen, which doesn't really take intricate technical knowledge, but has an annoying bug or issue with boot where sometimes you have to boot it a couple times for the graphics output to initialize cleanly. I also have a laptop with Linux, and it has a swollen battery, which is probably my biggest gripe, but I'm not sure of the degree I can or can't blame Linux for that - it seems like it started when the laptop fell about 3 feet to a hard floor. But yeah, no special technical knowledge required.
