So I think this is referring to the Steam Deck. Which (as you say) can support other Linux distros, it's not locked down to SteamOS. Or even other OS's if you wanted to.

I've only run SteamOS on my Deck, but afaik if you install it on something else then you can still flip it between the gaming mode and the desktop mode. In desktop mode it behaves exactly like you'd expect an Arch Linux install to behave, and you can mess around with it as much as you'd like. In gaming mode it's like a console and really only plays games (but isn't limited to Steam games - people have got it running emulators and all sorts of other stuff too).

Yes, this is Steam Deck, and the "gaming mode" of steam deck is essentially a submode of Steam Big Picture mode (used for TV-like screens).
