C|Net | at | by Mike

Microsoft released on Tuesday an upgraded version of a wireless optical mouse intended for laptop users and plans to introduce two new desktop mice--one laser and one optical--by this summer.

All of the new products rely on the company's High Definition technology, which is aimed at supplying improved mouse responsiveness, at least six months of battery life, and smoother tracking over uneven surfaces. According to a statement, Microsoft has sold more than 1 million products from the High Definition line since its debut in September.

The Wireless Optical Notebook Mouse 3000, which sells for $29, is billed as an upgrade to the company's best-selling Wireless Notebook Optical Mouse.
