New Logitech Dark Field Mice Operate On Glass

Slatterz writes "Logitech has introduced new mice that use two lasers rather than one to work on a variety of previously unusable surfaces. The first laser picks out imperfections in the surface of a tabletop while the second laser focuses on microscopic imperfections highlighted and uses those to direct the cursor. The technique, dubbed dark field microscopy, allows mice to be used on almost any surface, including glass (as long as it is more than 4mm thick)."

    Or perhaps we could stop with the pissing match and saying how mine's better than yours, and agree that it's a question of personal preference, and that people will choose what they want to choose?

    Perhaps you never learned the meaning of "to each his own", which I explicitly prefixed my comment with?
