Is it a mouseulator? A calcouse? Whatever you call this bastard child of a mouse and calculator, it's Canon's first model in its legendary X-series of calculators. Can I hear some love from the accountants, please?
The laser mouse is wireless, connecting to Windows and OS X machines via Bluetooth 2.0, and has three click-buttons plus a scroll-wheel. It's pretty much the antithesis to Apple's Magic Trackpad, but that just makes me love it more. It's most definitely a step or two above Canon's very first entry into this niche market, which looked like something more akin to a Brando production line error.
You're probably wondering the same thing I was, when I first saw this mouseulator. The number buttons can be locked when not in use, to avoid accidental equations by a heavy-of-weight palm. And, if you've already got a mouse that you can't bear to part with, the X Mark I mouse can also double up as a numeric keypad, with the mousing-function switched off.
