/>Too lazy to look for the calculator program on your PC? The Takumi computer key calculator could be the thing for you.
At first glance, it’s a standard calculator, but look closely and you’ll see it’s a numeric keypad, which you can hook up to your PC for power, working out basic maths via the built-in screen and basic calculation keys.
The calculator is available in a number of colours, including this rather nice off-white colour – ideal for those of us with old desktops. It retails for $65.22, which is around £33.
