Microsoft has upgraded its Wireless Notebook Optical Mouse with 'High Definition Optical Technology' tracking technology, which the company boasts puts its mice "two generations ahead" of other pointing devices. According to Microsoft, the Wireless Notebook Optical Mouse works at 1,000 dpi, captures 6,000 frames per second, uses a low-powered chip to conserve battery power, and offers smoother tracking on any surface.
For the desktop, the Wireless Laser Mouse 5000 features a five-button, ambidextrous design, a Magnifier button for real-time enlargement and editing of any section of the screen, and a Tilt Wheel that makes navigating and viewing detailed spreadsheets and documents even easier. The new Wireless Optical Mouse 2000 is an affordable high-performance mouse featuring High Definition Optical Technology, an ambidextrous design with silver accents and three buttons.

-- Improved responsiveness. With 1,000 dots per inch, all Microsoft High Definition mice deliver the right amount of responsiveness in relation to hand movement, requiring less hand motion in small spaces such as coffee tables or airplane trays.

-- Greater precision. Microsoft High Definition mice capture 6,000 frames per second to accurately track hand movement and prevent stopping or skipping, even when moving very quickly. The mice are equipped with a state-of-the-art chip, developed by Microsoft, which requires less power and maximizes efficiency, delivering an average of more than six months of battery life for wireless mice.

-- Smoother tracking. Proprietary Microsoft Intelligent Tracking System -- the brains of the tracking technology that reads the information the sensor is relaying -- means smoother tracking without interruptions or skipping, even over unique or uneven surfaces.
