Windows offers complete compatibility with all games. I get what they are driving at, but I am amused that I have older games running on Linux that do not run on windows. They should have said most games run on windows, and if you dont mind root kits installed on your computer anti cheat ones do too.
Xbox PC Game Pass provides access to a wide range of games. If you want a subscription. And a Microsoft account. Or in their case friends. And if you are going to share your pass with a friend, why not just sail the seas and call it a day?
Windows is more versatile than Linux, allowing your gaming handheld to also serve as a primary desktop PC with the ability to connect peripherals and a monitor, providing a full-fledged computing experience. This adds value to a Windows-based handheld. This one pissed me off. No it is not more versatile. I use the steamdeck as my work computer when I am out of town and I use Linux on the desktop exclusively. I have a full fledged computing experience, thank you very much.
