It should have happened sooner or later. After ruthless experiments on crossing a computer mouse with a phone, keyboard, remote control and other devices, the Chinese (most likely) comrades managed to combine it with a full-fledged calculator.

This thing, which is sold on PrezzyBox.com, resembles a mouse only remotely, although it has two buttons and a scroll wheel. The device can not boast of ultra-small dimensions, but on the road, probably, it does not pull too much. However, the convenience of using this gadget can hardly be said for sure.
It is worth about 30 USD.
