Accountant’s Tool

I like cool gadgets, and this one caught my eye.  If I were an accountant or a number cruncher, this external keypad would be crucial for me.   I have seen these gadgets before, but this one has more shortcut buttons on the side that would be handy.  On the otherhand, I like my screen real estate, and I prefer to use a laptop with a 17″ screen.  These laptops include a 10-key.
