Sounds like Proton and SteamOS are very successfully closing the gap with games. Ironically hardware pricing might be the reason SteamOS doesnt progress at the same speed that it has been as Steam machines are pricey.

Specialist software on the otherhand. I get that. Its the same reasonw hy I have a macboom for academic work and Windows for other work. Vendors not building across ecosystems is frustrating, though presumably thats due to tooling lock in.
