Laser mice
"In 2004, Logitech, along with Agilent Technologies, introduced the laser mouse with its MX 1000 model. This mouse uses a small laser instead of a LED. The new technology can increase the resolution of the image taken by the mouse. The companies claim that this leads to a 20× increase in the sensitivity to the surface features used for navigation compared to conventional optical mice (see interference). Gamers have complained that the MX 1000 does not respond immediately to movement after it is picked up, moved, and then put down on the mouse pad. Newer revisions of the mouse do not seem to suffer from this problem, which is a power-saving feature (almost all optical mice, laser or LED based, also implement this power-saving feature, except those intended for use in gaming, where a millisecond of delay is significant). Since it is a wireless mouse, the engineers designed it to save as much power as possible. In order to do this, the mouse blinks the laser when in standby mode (8 seconds after the last motion). This function also increases the laser life.
