Linux

Your hardware is incompatible

I think you'll have an extremely hard time finding any hardware that supports Windows but can't run linux. With Win11 requirements it's much more likely to be the other way around.

Your applications/games only work well on native Windows

Personally, every game I care to run works perfectly fine on my Steam Deck. I refuse to play any games that require kernel-level anti-cheat. It's officially distributed malware if you ask me.
