Buffalo presents these cool USB memory keys today. The RUF-Q16/4P are 4 small USB keys of 16MB each (very light, I know) in the shape of a CD and stored in some kind of spindle (just like regular CD’s). The spindle is included in the packaging, and the USB keys measure 60×9mm and weigh 12g. These cute keys will be available in Japan and on GeekStuff4U.com at the end of the month.
