The biggest threat to Windows is Steam

[JimmyFantasy]

I recently switched from windows 10 to a linux OS on my retrogame dedicated mini-pc.
Man, it was quite a boost in terms of overall performace, responsiveness and on system resource usage (cpu%, ram etc).
Considering it is an open-source OS driven by the community and not tied to any particular company, I think it should become the way to go for gaming and new derived OS like SteamOS.
