USB Mouse Calculator ready to calculate how much money you've wasted
There's plenty of mice with integrated keypads out there, but those looking for some more instant gratification with their calculations may want to consider this marvel of technology now being offered by PrezzyBox.com, which packs a full-on calculator into something vaguely resembling a mouse. For other number-intensive tasks, the mouse will also double as a numeric keypad, and it appears to be small enough to pack away with your laptop for some number crunching on the go. If that's what you've been waiting for, you can get your fix now for £15 (or just over $30), which is sure more affordable than Casio's non-mouse USB calculator.[Via Coolest Gadgets]
