The M515 sports a sealed bottom case that can glide on fabric (and stop fuzz from getting in) as well as a hand-detection sensor to make sure the mouse is only active when you want it to be. Thus, it can work anywhere on any soft surface from a blanket to a sofa cushion. Very versatile. (Still, can no one just get up and go to a table or desk anymore?)
Nitty-gritty details include a two-year battery life, Logitech's Hyper-Fast Scrolling technology and a handy USB receiver for your computer.
The Logitech Wireless Mouse M515 will roll out across Europe this April for £49.99 ($79.68). It looks like couch potatoes in America will have to wait a bit.
