Computer mice haven't gone through any major evolution changes during the years they have existed. So far the biggest improvements from the original design have been the invention of optical movement sensor that tracks the surface that the mouse travels on and of course the wheel. The optical sensors have slowly become more and more accurate but now a whole new level of accuracy has become available due to the laser technology. Instead of traditional led-based optical mice, there's a non visible laser beam in the mouse which - at least according to the manufacturers - should be more accurate than the led based technology. Now Logitech has sent us their G3 laser mouse and we can find out ourselves if there's any noticeable difference.
