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.
