The same Multi-Touch technology introduced on the iPhone and Mac notebook trackpads now comes to the mouse. Its called Magic Mouse, and its the worlds first Multi-Touch mouse. You can use it just like a normal point-and-click mouse and click anywhere on the surface. And you can use it for basic Multi-Touch gestures. Scroll in any direction, and swipe through images on its smooth, seamless top case. Magic Mouse works wirelessly using Bluetooth, so you dont have to worry about cables or adapters cluttering your workspace. The laser-tracking engine delivers responsive performance on many surfaces. And built-in software lets you configure Magic Mouse any way you want. Magic Mouse is included with every new iMac. Or add it to your existing Mac. Magic Mouse is powered by two AA batteries (included).
