Kensington Technology Group
has unveiled its seventh-generation Expert Mouse trackball, which includes the Scroll Ring. The Scroll Ring circles the ball to provide precise scrolling functionality.
It uses optical technology, has a smaller footprint than its predecessors, and a soft detachable wrist rest. The new Expert Mouse trackball is designed in a metallic black and silver color scheme.
The US$119 trackball comes with the Kensington MouseWorks software, which is compatible with Mac OS X and Mac OS 8.6-9.x. It lets you program the functions of the device’s four trackball buttons, saving clicks and keystrokes, shortening tasks, and executing repetitive commands.
