Mobile number crunchers whose laptop keyboard is lacking in a useful separate keypad will no doubt be interested to discover that Canon is about to release a new slim laser mouse which includes its own keypad. The new X Mark I Mouse could also please trackpad haters looking to reduce the number of peripherals housed within the laptop bag, as it also operates as a 10-digit calculator complete with LCD screen.

The X Mark I Mouse is a three-button (including the scroll wheel), 1200 dpi laser mouse that has a number pad where the palm of your hand would gently rest during use. You'll also notice a 10 character LCD screen just above the keypad which gives away the device's third useful function - it's also a calculator. Canon has also sweetened the deal by adding some green credentials to the pot.

It's just US$19 a year.


The lower casing and battery cover are made from plastic recycled from old Canon copiers. Granted, it's probably not going to win any prizes for ergonomics but as a space- and time-saver, it looks like a winner to me.

The 4.72 x 2.36 x 1.06-inch (120 x 60 x 27 mm) mouse wirelessly connects to a laptop via Bluetooth 2.0 - so you don't even have to worry about blocking up a much-needed USB port with a nano receiver - and is Windows and Mac compatible. It weighs 3.74 ounces (106g) with two AAA-type batteries (included), and comes in either black or white.

Canon says that the X Mark I Mouse will be available from next month for an estimated retail of US$60.
