Brando's new USB Wireless Keypad is probably just what you're looking for, if you're looking for a wireless keypad, of course. It's got the standard keypad keys, 13 hotkeys, and a totally sweet built-in trackball. It's no Optimus Aux, or anything, but we imagine this pad will be best put to use whilst counting huge piles of coins (or any hard currency) in a public library or adding up intense columns of figures on the subway. 3,700 coppers and it's yours.
