Apart from all the other benefits, one underrated feature of SteamOS over Windows for a handheld is how GameScope handles windows:

On Microsoft Windows, if a game from 2008 boots a menu for configuration before the game itself, it's usually this tiny Windows 98 square that you need pinpoint precision to maneuver. Worse still, if a launcher or firewall or whatever decides to pop up a window on top of your fullscreen game, the screen flashes three times, the mouse focus can attach itself to the wrong panel, and it can be super annoying.

On SteamOS, any window will scale to your full screen size - including those ancient ones. There will be no firewall or defender or whatever prompts, but if a game launcher does decide to spawn a new window, focus is not lost and changing between windows using the Steam button is simple, fast and the input will always work on the correct window.

It's the absolute best way to turn PC software into a console experience. Windows solution to this same "how to make a PC feel like a console?" is adding yet another layer on top of everything with the GameBar, then make it inconsistent by changing the UI on gamepads, then make it even more inconsistent by changing your saved layout after every update. The GameBar fixes zero issues.
