Most might consider the need to operate a mouse on a glass surface a rather moot and gimmicky marketing feature, but not me.  I hate my mouse pad and feel like I have a doormat living on my desk.  I present to you the Logitech Performance MX mouse.  It uses a technology called Darkfield Laser Tracking technology, which I assure you won’t annihilate any humans but reflects the laser off the imperfections in the glass; one caveat though, the glass has to be at least 4mm thick.

Dvice got their hands on one and did a little video demo.  Although the video shows it clearly working, if you look closely there is a bit of juttering when the Performance MX mouse is being used on glass, leading me to believe that the tech is not 100% sound.

The Performance MX mouse will be available later this month along with the smaller Anywhere Mouse MX for $100 and $80 respectively.
