In that case I will have to disagree. I run a stock, up to date Ubuntu. Yes, there is a GUI for a lot of things, but I will most certainly run into something that will require me to drop to the CLI before long – which I am fine with, but I am not going to pretend it won't inevitably happen.
My experience is: On Windows, for most enduser use cases (and this absolutely excludes anything dev related), I would expect the user to get by without touching the CLI. In fact, I would assume that any given application will expose all of its functionality only through a graphical UI. For me, on Linux, the opposite expectation applies.
