A lot of older PC games can run just fine on modern phone hardware. I’d buy a SteamOS version of a phone that has some modular or built-in set of buttons and analog sticks. I don’t know how the app ecosystem would work for sensitive things like banking but it’s mostly a minor issue for me.
No, because I don’t care about gaming on a phone. But I’d love to have numerous viable Linux phone alternatives to break the cartel duopoly.
