A4Tech, a Korean retailer, announced an optical mouse designed to work in any surface, including the clear ones. The Glaser Mouse X6-70D gets along with desktop surfaces, mousepads, pant legs or freshly-cleaned glass. It features a '2XClick button', so consumers can programme the mouse to play softwares with just one click, instead of double click. It also has an 'Office' button that launches a map with pre-programmed softwares to be easily accessible.
