We have already seen a couple of uber calculators, like the Robot or the Giant Talking Mat, but the Lexon Roswell Calculator beats them all in the style department.

Like you can see on the image it has a transparent screen that displays the info and makes all the difference when comparing to other calculators – it really gives another feeling to the small gadget. Another interesting detail is that the Roswell calculator is made from a single piece of aluminum.

Large screen with two lines capable of displaying ten digits in each, with keys for calculating currency conversions, percentages, memory, and other computations.

Price: £33 (close to $65)
