Apologies. Allow me to clarify.

I meant that it’s not harder than Windows, when it comes to playing games. And I even made that claim stronger by proclaiming that it’s probably even easier.

Edit: SteamOS is the operating system found on the Steam Deck. It’s basically Arch Linux (btw), but with Valve’s (very) special sauce. It’s what you’d expect from your average game console; which is a good thing*.
