Interesting comment from DanBricklin (inventor of the SpreadSheet) : http://radio.weblogs.com/0114726/2003/04/10.html

Bricklin explained that his father was a printer and that's how he learned the importance of prototyping, doing quick mockups for customers first before you committed to stuff that was hard to change. He showed a manual page from a typesetting terminal, the Harris 2200, that also served as one inspiration for the spreadsheet, with its separate layers of data, calculations and formatting. He also mentioned that it was his background in computerized typesetting that inculcated in him the principle of "keystroke minimization" – because in that field, people were actually paid by the keystroke.
