Here’s a combo gadget that seems like a pretty good idea on paper, but I don’t know how practical it really is. This USB device from Lexibook mixes an optical mouse, a calculator and a numeric keypad in a single package.
It’s got a full calculator with an LCD screen and the mouse even has a scroll wheel. Ergonomically, it definitely looks a bit sketchy. While I really like the idea of being able to do some quick math on the fly, I’m concerned that I might accidentally press some of the keys while “mousing.”
The mouse is compatible with Windows, Mac and Linux computers, and UK retailer Prezzybox offers ’em for £14.95 each (appx. $30 USD.)
