Switching to Linux is great and easy. As long as nothing goes wrong. The second something goes wrong, you need to climb a very daunting learning curve.
That's also more on to who the user is (how they interact with the device.) IMHO it's valuable to at least get to search the internet with an error message. I switched over a decade ago, but on Windows all I had was hexadecimal codes or vague messages. I was a power user, fiddling with all sorts of software, and things did break on either side. I stayed where I could learn, a steep curve, sure. But not a wall.
