Buffalo declared on Wednesday that it had developed the RHW-01, a USB travel mouse which uses the iPod's distinctive circular scroll wheel to aid in navigating websites or other long documents. The design saves repetitive strain on the user's finger by allowing for a continuous scrolling motion and also conserves space, Buffalo writes. Its shallow, aluminum shell is only 8mm tall and weighs a single ounce.

The company claims to provide further convenience through the cable mechanism. A single button press automatically retracts the USB cable, storing the plug closely to the mouse body for easy storage in a travel bag. The RHW-01 uses an 800 DPI optical sensor for added precision. Black, silver, and white editions of Buffalo's mouse will go on sale in mid-December for $58.
