Apple has introduced a wireless Mighty Mouse, claiming that the Bluetooth-enabled device features a laser tracking engine 20 times more sensitive than a standard optical mouse for better tracking on a variety of surfaces.

The Bluetooth 2.0 device retains the simplicity of Apple's long established single-button mouse, but can be configured with additional buttons depending on the preference of individual users.

Priced at $69, the mouse features a single seamless enclosure with programmable touch sensors that can be set as primary or secondary buttons.

Up to four independently programmable buttons can be configured, in addition to a 'scroll ball' that lets users scroll in any direction.

"We have cut the cord on our popular Mighty Mouse to give consumers even more flexibility when using a Mac," said David Moody, vice president of worldwide Mac product marketing at Apple.

The device 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. It works with one or two AA batteries.
