The aim with the trackball is improved comfort when working as with a trackball, a user doesn't need to move his or her arm when moving the cursor. It's also much more portable as Logitech asserts that it can be used "wherever you want," from desks to "lumpy beds."
Additionally, the Unifying wireless receiver can stay put in the laptop, and the 2.4GHz wireless connection can survive from up to 30 feet away.
Some of the other additional touches include a scroll wheel plus back/forward button for further control. Finally, the M570 is powered by a single AA battery, producing a staggering 18 months of battery life.
Available in both the U.S. and Europe now, the M570 is retailing for $59.99 and €69.99 respectively. To see the Logitech Wireless Trackball M570 in action, check out the promo video below:
