Microsoft's Wireless Notebook Optical Mouse wasn't broken -- in fact, it was the company's best seller -- but Microsoft's fixed it anyway. The new and improved Wireless Notebook Optical Mouse 3000 ($30) boasts Microsoft's proprietary High Definition technology for smooth, precise tracking in small spaces on virtually any surface, as well as a smaller receiver that makes the traveling gadget easier to stow in a briefcase or laptop bag.

For desktop navigators, the 1,000 dots-per-inch, 6,000 frames-per-second High Definition design also stars in an affordable ($30), ambidextrous Wireless Optical Mouse 2000, a silver-accented mouse with three buttons. A new Wireless Laser Mouse 5000 ($50) combines the high-tech tracking with a laser- rather than LED-based, five-button model featuring a Tilt Wheel for sideways scrolling through spreadsheets and documents and a Magnifier for real-time enlargement and editing of any section of the screen. The Wireless Notebook Optical Mouse 3000 is now shipping, with the Wireless Laser Mouse 5000 due later this month and the Wireless Optical Mouse 2000 coming in June.
