today introduced its Cordless Optical Mouse for Notebooks ($40), which uses an ultra-slim, key-sized USB receiver for connectivity. The compact, ambidextrous design sports an elegant silver finish, employs an optical sensor to track movement, remains connected to its receiver unit when unplugged, and uses 27MHz Fast RF Cordless technology for connectivity up to six feet away. It features three programmable buttons, including a middle button that also serves as a scroll wheel. It has a five-year limited warranty and is compatible with Mac OS 8/9/X.
