We all are quite used to mouse these days. Mouse has greately improved to wireless mouse, portable mouse usb mouse etc but the history of this tiny gadget dates back to some 40 years back Logitech came with the first ever commercially available mouse in 1982. An opto mechanical one, it was made to provide a greater tracking precision then the traditional mechanical mouse and came with the tactical response of a rolling ball. Then the shape changed to square shaped mouse around 1986 with a single button. Now we got as many as 6 buttons and scrollers available with LED base for less power consumption and greater precision.
This mouse looks like tom cruise in Mission Impossible.
