Apple Magic Mouse
Description (from B&H): The Magic Mouse from Apple is an innovative wireless mouse with a seamless Multi-Touch surface. Boasting wireless Bluetooth technology, the device represents a revolutionary step in mouse design. A true Multi-Touch device, the mouse doesn’t need a scroll ball, clunky click wheel, cord, or visible buttons.
You can control all aspects of your cursor with Multi-Touch gestures, just as you would on a MacBook Pro trackpad. The entire surface of the mouse is a button, allowing you to click with ease. Use two fingers to right click, and simply slide your finger across the mouse’s smooth surface to scroll through documents. Holding the control key while scrolling allows you to magnify your screen, and the two-finger swipe gesture allows you to move forward and back in iPhoto and Safari. You’ll swear that it’s magic.
