Apple's Magic Mouse first came on the scene in 2009. It's the first mouse available for consumers to have multi-touch capabilities similar to the way a trackpad functions on the MacBook Air and MacBook Pro.
Apple pioneered the use of the mouse for personal computers when the Macintosh debuted in 1984. Eventually Microsoft developed Windows to counter and introduced the mouse to PC users as well. But one philosophical difference remained apparent: Mac users got by with one mouse button, while PC users had two or more.
Over the years Apple redesigned its Mac mouse over and over again, eventually acquiescing to critics who said the one-button design was too simple when in 2005 it introduced the Mighty Mouse, a multi-touch mouse with an integrated trackball in place of a scroll wheel.
The Magic Mouse was succeeded four years later by the Mighty Mouse, which now comes as standard equipment on the iMac line. It communicates with the Macintosh using Bluetooth and is powered by two AA batteries.
As long as you're running OS X Leopard 10.5.8 or later, you can use the Mighty Mouse with Apple's built-in drivers.
The surface of the Magic Mouse is one unbroken plane, curved to fit your fingers. The entire surface depresses to produce a click action, but sensors underneath the surface can differentiate your fingers' position and movement. As a result, you can use the Magic Mouse to left or right-click, scroll in 360 degrees, zoom, pan, and swipe all by making gestures on the top of the mouse.
Recent versions of OS X have incorporated mouse settings in System Preferences that enable you to view short videos of how each gesture works, with the ability to activate and deactivate specific settings to customize the experience for your use.
What's more, the Magic Mouse is a totally ambidextrous design, so it'll be as comfortable for a lefty as it is for a righty.
If you don't have an iMac, don't fret. The Magic Mouse is available separately and works with any Mac equipped with Bluetooth and OS X 10.5.8 or later. It costs $69.
