Quotesteam deck is just a bad pc disguised as a handheld (too bulky to actually carry around, 2hr battery life, seen zero of them outside, but have seen quite a bunch of switches)
A "bad PC" that allows any random schmuck to both game and do light non-interactive work like email reading or video watching in virtually any place, while also becoming a full-fledged working computer to do text collaboration, code writing, video editing or competitive gaming with just a few external peripherals...
Is a PC good enough for a good 70% of the whole market of "people mixing use-cases on the same hardware for practical or financial reason". xd
