One of the new, notable items that Apple released this week is the Magic Mouse, the first multi-touch mouse. The Magic Mouse will come standard with new iMacs, but you can get one for your existing Mac for $69.
The multi-touch surface covers the whole Magic Mouse, just one smooth surface that can sense things like swipes, scrolls, etc from your fingers. The entire mouse is a button. It can also tell when your hand is just resting on the mouse.
The included software lets you re-assign gestures, and assign handedness. Magic Mouse is wireless Bluetooth and has a 33ft range.
You can see a video of the Magic Mouse in action at Apple’s website.
