You can do nearly everything you need to via the GUI on the major distros (the ones that most people would use). There's plenty of things on Windows you must use the command-line for.
And anytime you need to use the Run dialogue it's the same argument. It's the same "issue" of having to type instead of using your mouse.
And if you don't need to use the command-line on Windows, it's the registry. The awful, terrible, horrible, disgusting registry.
I'm not actually sure what on earth you mean with "not supporting right click". Maybe you're thinking of older Mac versions?
It has been for a while now.
