Logitech Cordless Number Pad

I have to admit, as a laptop user, the one thing that I miss is having a number pad at my fingertips. Something tells me that if I'm experiencing this, then I am not alone.

Fortunately, Logitech has you covered with a number pad that attaches to your laptop conveniently with a USB key. Now if you want to input a bunch of numbers with one hand, you can do it.
