Canon X Mark I | 4738B001AA

Now you can blend three functions in one ingenious device. The X MARK I MOUSE is a high performance wireless laser (1200 dpi) mouse, a convenient 10-digit calculator with decimal point selection, and a numerical data entry tool for your PC or Mac: all at the same time.
With integrated Bluetooth 2.0 connectivity, three click buttons and a fully functional scroll-wheel, the wireless mouse provides users with the ability to maneuver and control their computer. Carrying out mathematical calculations is simple using the calculator, without the need for a separate device - a great way to keep desks from becoming cluttered. And thanks to its direct link to your PC or Mac, the calculator also acts as an incredibly convenient data entry tool.
