The Mighty Mouse's tracking engine is based on powerful laser technology that delivers 20 times the performance of standard optical tracking, giving you more accuracy and responsiveness on more surfaces. It works just as well on your office desk as it does on a table at your favorite coffee spot without a mousepad. The Might Mouse combines the capability of a multibutton mouse with Apple's signature top-shell design for both form and function. Mighty Mouse's Scroll Ball features miniature sensors that allow you to manipulate what appears on your screen merely by moving your finger. The 360-degrees scrolling perfectly positions to roll smoothly under just one finger. Touch-sensitive technology under Mighty Mouse's seamless top shell detect where you're clicking, transforming your sleek, one-button mouse into a two-button wonder. Pan images in iPhoto, view timelines in iMovie HD and Final Cut Pro, traverse bars in GarageBand and Logic Pro while sipping your morning cup of coffee or typing. Pre-programmed to launch Dashboard, Mighty Mouse's side buttons show you all your open windows in Expose with a squeeze. Mac OS X gives you the capability to choose any application from the intuitive System Preference pane.
