I don't think it requires a larger time investment. It is really hard to remember how much time you've spent learning windows. Windows is easy not because it is so user friendly, but because you are so used to it. A modern gnome these days is very user friendly and a lot of what you've learned can be applied there too. Things generally are quite straightforward, more so than on windows, at least on the happy path.
