I have been a user since around 2000, I work in Linux every day, and I get where you're coming from - but in the context of gaming Linux has really only recently come into its own.

Like, could you imagine, circa 2010, telling a naive user that practically their whole Steam library would work with one click? Wine has always been a minor miracle, but at some point there was an inversion between being surprised when it worked, and being surprised that it didn't work...
