MacMice today announced the availability of its Optical Mouse for “Macintosh users who like the design of Apple’s Pro Mouse, but who want to enjoy 2-button and scrollwheel functions.” The mouse has a scroll wheel and a 1-piece clear acrylic outer housing that tilts left or right to provide true 2-button functionality in a stylish “buttonless” design. It also features a USB-powered blue LED under the scroll wheel, and operates natively under Mac OS X (free driver available for Mac OS 8/9 users). The MacMice Optical Mouse is available in black, silver or white inner colors for US$39.99.
