Still I’m not convinced of Steam OS compared to Windows 11, since I would like to play also Epic games and maybe some emulators
You can actually play games from Epic Games and other stores on Steam Deck with Lutris or Heroic Games Launcher (or a few other options) and you can install emulators on it too, it has a desktop mode, so you’re not locked into only Steam stuff. Also, you can put Windows on the Steam Deck too as an option if you prefer, I don’t know many people who have but the option is there.
