Ha! In my early days of computing, when we had to walk to school uphill both ways, 5 miles in the snow, going from punch cards in 1977 to line editors was fantastic, I first used original "ed" in 1978, with it's one error message of "?" (it was developed in the days when 110 baud Teletype terminals put an extreme premium on every character typed and printed), some random ones in micros, then EMACS was a fantastic improvement in 1979-80. And I haven't looked back.
