The first mouse had the cord in front, but only for a little while. A small rounded box less than the size of one s hand, it had to mounted discs on the bottom. The device could be tilted to draw perfect lines. Today s mice solve that with a rubber ball against two thin cylinders. It is unlikely that the mouse will lose its position any time soon.
Touchscreens require to much wasted movement.
Voice Recognition, while handy for word processing, doesn t allow for very convenient cursor control. And so it seems that the lifespan of the mouse will be limited only by the lifespan of the computer itself.
