I am not aware that you are able to use SteamOS on anything that isnt an AMD CPU and GPU (only APU?).

If it’s not yet generally available for any hardware combination it would be very tempting to switch.
Already used the desktop of the deck quite a bit to customize some behaviour (automatic start of syncthing after (game-mode) boot to sync save states to my PC, EmuDeck, emulators in general)
