> Many of its users were using terminals Perhaps an example will be more vivid. In the eighties most people who were on the internet worked on a 24 line by 80 column terminal. Some people used Emacs buffers as a predecessor to multiple windows on large screens: - Edit your code, perhaps splitting the screen in two buffers to look at different files or places in a large file. - Split yet again one buffer for compilation error messages. - Split the other one for a shell subprocess to run the program, check mail, etc. Basically all-Emacs all day. Not my setup, but I saw it done often enough.
