Apple has formally launched its wireless Mighty Mouse.

Based on Bluetooth 2.0, the new wireless Mighty Mouse offers a reliable, secure connection to Macs and features a new laser tracking engine that is "20 times more sensitive than standard optical mice for better tracking on even more surfaces", the company said.

It costs £49 (including VAT). Features include up to four independently programmable buttons and the Scroll Ball.

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

The wireless Mighty Mouse features a single enclosure with programmable touch sensors that act as primary or secondary buttons. Two programmable buttons are activated by pressing its Scroll Ball and squeezing its sides.

The mouse is built for both right and left-handed users. It also includes an advanced power management system that automatically switches to low power modes during inactivity, and an off switch to maintain battery life when not in use. Ready to use out of the box, the wireless Mighty Mouse works with either one or two AA batteries.
