To be honest, the line between Windows and Mac is becoming so thin that I suspect many people who aren't reliant solely on applications would have less issues with switching. Even the gestures are incredibly similar and just as natural, the same applies to the Trackpads on a Surface Pro, Book or Laptop. I'm a Mac user and while I did switch back to Windows a back a couple years ago I had to switch back for Sketch (Mac Only App) otherwise I would've remained on a PC. Now, I don't really have much issue transitioning between the two, it just seems kind of seamless in a way.
