#mouse

From John Markoff’s tribute to Douglas C. Engelbart, who passed away this week at the age of 88:

Early versions of the mouse had three buttons, because that was all the case could accommodate, even though Dr. Engelbart felt that as many as 10 buttons would be more useful. Two decades later, when Steve Jobs added the mouse to his Macintosh computer, he decided that a single button was appropriate. The Macintosh designers believed in radical simplicity, and Mr. Jobs argued that with a single button it was impossible to push the wrong one.
