I'll keep repeating this. I've been doing "installing operating systems and intro to IT courses" for well over a decade now, for many different types of users at many skill levels.
Out of the box Linux (e.g. Mint) is an across the board better operating system for anyone who doesn't need anything specifically tied to Windows. It's easier, it just works.
I admit that it's not all "Linux people are awesome" as much as I would like -- it's "most everything most people need is available on the Web," which Linux is very good at.
The Linux experience is roughly equal to the Mac experience, and Windows is third. Inertia is presently Windows Desktop only advantage.
