To elaborate on my question take the Steam Deck, which is designed as a handheld console, however, does have a "desktop" environment and can be used as a PC. From the tour I understand that questions about the Steam Deck would be on-topic, as it's gaming hardware, but what if the question itself isn't about games on the device?
For example, what if someone wanted to know how to install a PDF Reader on the device and (maybe) then use that within "gaming mode"?
This isn't limited to the Steam Deck, I've just used it as an example. If I recall correctly, an Xbox can (or could) have Windows Apps installed on it if you are in developer mode, so if someone was asking about that I assume that could be on-topic too.
I note that questions about Discord appear to be on-topic, so would the answer change if the question were about Discord and the console/device?
