People will put more effort in installing Windows on the Steam Deck than learning how to use Linux

That’s kinda the beauty of the Steam Deck, no? It’s a pretty open platform. Someone who wants to dig into the system can go to desktop mode and use a full Linux OS. Someone who wants to use Windows for whatever reason can install and use it. Someone who wants to treat it as a console can just stick to game mode and never care what OS their console runs, much like how a Switch user doesn’t care what’s behind Horizon.
