A device used by a tightwad co-worker in response to other coworker's new Blackberrys. It is composed of two parts: a piece of paper folded into a pocket-sized pad, and a pencil. The upgraded Whiteberry replaces the pencil with a more expensive writing utensil, typically a ball-point pen.
Jim: Why does Rick constantly pull a piece of paper out of his shirt pocket whenever our boss tells him something?
Dave: Oh, thats just Rick's Whiteberry.
