Computer Keypad Calculator
Instead of going for yet another one of those attempts of putting a calculator inside a computer mouse, like Ezkey, Sanwa, and others have tried, the Japanse company Takumi decided to try something different by designing a calculator like a keypad.
The result is a geeky cool looking calculator which can be connected to the USB port of your Windows based computer. It measures W84×H140×D23 mm and is available in white, black, red and beige.
The Takumi Keypad Calculator costs ¥5250 (about $46 USD) at caina.jp.
