Apple announces wireless Mighty Mouse

Apple on Tuesday took the wires off its multi-button scroll-wheel Mighty Mouse. According to Apple, the new mouse features a new laser tracking engine that is 20 times more sensitive than standard optical mice for better tracking on even more surfaces.

The Mighty Mouse is Bluetooth 2.0-based, keeping the same design elements of the original mouse. Apple said the mouse also includes an advanced power management system that automatically switches to low power modes during inactivity, and an off switch to maintain battery life while not in use. Apple said the wireless Mighty Mouse works with either one or two AA batteries.

The wireless Mighty Mouse is available immediately for $69.
