Canon introduced a new 3-in-1 USB mouse. Yep, according to our extremely confidential sources, Canon engineers who are working on the future 5D failed to come up with anything better than a mouse …..

Seriously, you can use it as a standard mouse, of course! It can also be used a calculator when you open it! It sends calculator results to your computer, and can be used as a numeric pad. It comes with an optical sensor of 1000dpi.
