Yeah, linux is my main OS.

No, you don't have to be enthusiastic about the command line. But it's not going anywhere if you change your mind.

A great text that may help to explain things is "In the Beginning was the Command Line." The author does go off on a diatribe or two, but does a really good job explaining what you lose and what you gain when you start using a GUI.
