We've all been there: Killing time in the Apple store. Fidgeting with the iPhone on display. Marveling at the assortment of iPod colors. Cruising the net on the MacBook. Scoping out all the hotties [1] hitting up the genius bar for software upgrades. Or, if you're "that guy," using iSight to play King Kong licky-licky with another customer in the store — without that customer having a clue. Good work.
