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.
Just to get away from Apple and Google.
I love the trend towards Linux phones. I hope that gets a good enough foothold for me to get one.
