The new pointing device features up to four independently programmable buttons.
Mighty Mouse also introduces a Scroll Ball that lets users scroll in any direction-vertically, horizontally and even diagonally. With the Scroll Ball, users can scroll with natural, fluid movements, according to Apple.
Mighty Mouse is the first multi-button mouse that retains the simplicity of a single-button mouse, and can be used as a single- or multi-button mouse depending on the user's preference. Mighty Mouse features a single seamless enclosure with programmable touch sensors that act as primary or secondary buttons. With a click on the upper right or left side of the mouse, users can instantly access features such as contextual menus found in Mac OS X and other applications.
Mighty Mouse's two other buttons are activated by pressing its Scroll Ball and squeezing its sides, and can be easily programmed to give users one-click access to Mac OS X version 10.4.2 "Tiger" features such as Spotlight, Dashboard and Expose, or to launch any application such as Safari or iChat.
"With Mighty Mouse, we've simply built a better mouse," said David Moody, Apple's vice president of Worldwide Mac Product Marketing. "With its innovative Scroll Ball and unique integration of multiple buttons, Mighty Mouse adds functionality while retaining the elegant, easy-to-use Apple design."
