Sure, now, but back in the dark ages of 1992, basically nobody at my university had heard of vim, so we just got vi, which didn't have such a helpful prompt. After entering vi, I spent about 15 minutes alternately trying to do anything useful and cursing at it until a helpful grad student next to me pointed me at emacs. When I fired up emacs, by contrast, it had a helpful message telling me to type C-h t, which ran me through a nice little tutorial on how to use it, including C-x C-c to exit.
