The Mighty Mouse combines the performance features of a multi-button mouse with a design typical for Apple devices and thus represents an intelligent blend of form and functionality. According to individual use, the mouse can either be utilised as single-button or multi-button mouse. This is made possible through touch-sensitive sensors located in the one-piece housing. The sensors are capable of recognising what part of the mouse the user is clicking, and can thus change function from a single-button to a dual-button mouse. The pressure-sensitive buttons located on both sides can easily be operated with thumb and ring finger and allow a quick activation of Dashboard, Exposé and additional adaptive functions of the Mac OS X Tiger. A scroll ball positioned in the centre allows flexible navigation through the most diverse applications.
