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 60x9mm and weigh 12g. These cute keys will be available in Japan and on GeekStuff4U.com at the end of the month.
