This mouse connects to your laptop via Bluetooth wireless
technology, so there's no wire or separate adapter to worry about.
Pair Magic Mouse with your Mac and enjoy a reliable and secure
connection up to 33 feet away. When you combine Mouse with the
Wireless Keyboard, you create a workspace free of annoying cables.
And because Mouse is wireless, it can venture beyond the confines
of your desk. A quick flick of the on/off switch helps conserve
battery power while Mouse is tucked in your bag. Even when it's on,
Mouse manages power efficiently, by detecting periods of inactivity
