The magic is in the Multi-Touch.
The new Magic Mouse redefines what a mouse should do. In addition to its smooth, seamless top-shell design that acts as one button or two, Magic Mouse features a Multi-Touch surface with gesture support. Scroll vertically, horizontally, and diagonally — a full 360 degrees — simply by touching anywhere on the top surface. With a greater surface area for scrolling, you can get around a long timeline in iMovie, through a lengthy web page in Safari, or around a set of images in iPhoto more efficiently. You can also swipe through pages in Safari or photos in iPhoto with two fingers. It’s the most advanced Apple mouse ever made.
One or two. Left or right.
The seamless, one-button design of Magic Mouse makes it simple to use right out of the box. But if you want the functionality of a two-button mouse, that’s easy, too. Just change the configuration in System Preferences. And the ambidextrous construction means Magic Mouse is great for lefties or righties.
