I am sure there are lots of folks out there who have repetitive stress injuries, like carpal tunnel from things like typing too much or spending excess time surfing porn and fwapping. If you have that sort of issue and need an alternative to a mouse Logitech has a new Wireless Trackball M570 that might be just for you.
The M570 looks like a mouse with a big blue ball on the side. That ball is what controls the mouse pointer on the screen and you can swirl it around using your thumb. The M570 also has a scroll wheel, two mouse buttons, and two more buttons on the side.
The wireless device connects using a nano receiver and the batteries promise up to 18 months of use per set. The M570 might also be a good thing for users who have too little workspace for a normal mouse. The M570 will work with Windows and Mac computers and can be pre-ordered for $59.99 (USD).
