Maybe it is just us, but it seems that for ages the ubiquitous mouse did not change much: it had a ball, maybe two buttons and a third button if you wanted something fancy. Then things started to change. The ball was replaced with an optical sensor, more buttons were added to the side and a wheel started showing up on the scene. As things progressed we went from ball based sensors to optical to laser and now we are even seeing dual laser mice. Customizability via software was added and now profiles can even be stored directly on the mouse’s on-board memory. Truly, mice have come a long way even though the basic interface between you and the machine in front of you hasn’t changed much in the last 15 years.
