Have a look at the Steam Hardware [and software] Survey [0] results. Linux has been trending upwards whist Windows has been trending down for a wee while. And the population this looks at is primarily interested in gaming, which means that this is despite a compatibility layer being needed for a large amount of the software used. I imagine in other communities (software, old people) it's trending much faster.

E.g. I recently installed Linux Mint for my grandma so she could use email and an up-to-date web browser on her old laptop that can't run (secure) Windows anymore. The UI differences are marginal for her, and she can do everything she needs to much better than she could before (which was not at all).
