Now ain’t this a hoot – the Takumi Computer Key Calculator gets a modern update compared to boring old calculator designs, featuring keys from a computer keyboard that makes you feel as though you were punching in those figures from a standard numeric keypad. This battery-opeated device does not only work as a standalone device, it can also be connected to the PC via USB to function with Windows and other Windows-based software, doubling up as an impromptu number pad. The Takumi Computer Key Calculator will come in white, black, red, and beige colors, retailing for approximately $46 a pop.
