Steve Jobs' great displeasure about the the idea of a multi-button mouse was apparently the driving force behind Apple's push to greatly innovate in the area of input devices, according to a new interview with Apple's former Senior Mechanical Engineer of Product Design Abraham Farag (via Cult of Mac). Farag, who is the current owner of product development firm Sparkfactor Design, says that he was brought onboard to Apple in 1999 to design a successor to the original Apple USB "hockey puck" mouse, which shipped with the iMac G3 in 1998 and garnered heavy criticism for its small size, short cord, and tendency to rotate in a user's hand.
