Microsoft Intellimouse Explorer: Big Clunky Beastie
9 October 2000
Summary: The Microsoft Intellimouse introduces a novel way of tracking your mouse movements. Rather than opting for the traditional rotating ball method seen in most mice, Microsoft has developed an optical system. The mouse's movement is tracked by a red sensor at the bottom which detects minute variations in the surface upon which it is being used.
Pros: don't have to clean the ball, glows in the dark(?)
Cons: tacky silver colour, very uncomfortable to use, pricey
