I remember sitting down at a VMS terminal for the first time (a university library's terminal had trouble with its OPAC and dropped me into a logged in VMS shell). In fifteen minutes I had learned how to work with it, had the machine show me the university's network, and started to feel comfortable. I cannot imagine a similar experience if exposed to a Unix shell for the first time.
