What happens when Apple introduces a square-shaped new iPod and adorns it with an analog watch face for a lock screen? A whole new cottage industry sprouts up, whereby entrepreneurial types dust off old and mostly worthless watch straps, cut out an iPod nano-shaped compartment in them, and charge you $19.99 for the privilege of turning your tiny PMP into a somewhat bulky wristwatch. The saddest part about this is that we've got a feeling they might be on to a winner here.
