Yes, not everything needs to work. But everyone needs the things they want to work, if that makes sense. In other words, everyone has different requirements.

I require SteamVR to run acceptably in order to play VR games on my main computer. I have yet to find a distro that satisfies this requirement, so I must use Windows since it is the only thing that works for that use case.
Conversely, I do not require VR support on my laptop. Everything I want to do with my laptop can be done to an acceptable level with Linux, so I run Linux on my laptop. Simple.
