"According to Logitech, the Performance and Anywhere [mouses] use dark field microscopy to detect microscopic particles and micro-scratches on high-gloss surfaces, rather than tracking the surface itself. The mouse sensor 'sees' the clean areas of glass as a dark background with bright dots and then interprets the movement of the dots to precisely track where the device has been moved. The Logitech Performance Mouse will be available in the US and Europe in August for $100, while the mobile-friendly Anywhere Mouse is expected to retail at $80." I don't know how many times I've cursed shiny new desks and wished that someone would finally utilize that dark field microscopy technique (end bad humor). Thank heaven for Logitec finally breaking through.
