I just got a steam deck and I'm surprised how well it runs games. It's not quite as refined as a switch but it can run games were designed to run windowed in Windows with a mouse and keyboard. It can translate the game to run on Linux, the inputs to a gamepad and convert the game from being windowed to fullscreen. It's impressive and if the games were actually designed for the deck I feel like it could feel as seemless as the switch.
It is really making me consider Linux for my desktop once Windows 10 reaches EoL. The only game I've found that doesn't work is Destiny 2. Even the desktop mode on the deck is surprisingly nice
I switched to Bazzite on my main PC at the start of September and it's been great. I only use Windows for steam link vr streaming
