As mentioned in another comment, I use a Steam Deck which runs Linux, and I love that, but Steam OS isn't available for non-Decks yet in a fully supported manner.

I have enough programming adjacent hobbies (and I'm a SWE/SRE at work). Windows is requiring too much management, and I don't want to move to a DIY gaming setup on Linux, I'd rather wait for Steam OS to be fully supported, or just buy a console.

And before someone pushes back with Linux being easy to manage, that's not really the point. I use Linux, it requires more sysadmining than my Steam Deck does. Just because I can do it doesn't mean I want to.
