As long as optical mice have existed, it's been known that they don't work well with glass surfaces. That's always been a shame, since there are some really nice glass desks out there. Well, you won't have to worry anymore, because Logitech is going to release mice that will work on glass surfaces. Plus, there's that whole unifying USB thing that will reduce the amount of USB receivers that you'll need.
We've posted hacks on how to use your optical mouse on your favorite glass desk, but it's just more convenient to have them work on any surface. It's just annoying to have to use something as archaic as a mousepad in order to make your mouse work on glass. It's hard, but you had to get by with whatever worked.
It won't be a problem anymore and you can kiss that mousepad goodbye, because Logitech has just announced the release of a new mouse will will work on glass! The Performance MX mouse uses something evil named Darkfield Laser Tracking technology to track its way across any transparent surface. This technology works by reflecting the mouse's laser off imperfections in the glass, which just needs to be a mere 4 mm thick, in order for this to work. This means that it will work on any transparent surface. This mouse also comes with Logitech's new unifying USB dongle, which works with more than one wireless device from Logitech, kind of like the integrated Bluetooth of your laptop. The Performance MX will retail for $100. It's smaller portable brother, the Anywhere Mouse MX, will cost $80. They will both be available later this month.
