I think you might be thinking of the reason the 128K Mac didn't have a terminal. In that case, they wanted to force developers to make new, graphical programs instead of just porting their terminal programs to the Mac. The mouse had one button [to cater to users][1]:

The original Mac did not have arrow keys on its keyboard. This was to encourage programmers to write programs that use the mouse. I'm pretty sure I read this originally on http://www.folklore.org, but I can't find that particular story right now.
