From Apple's iPod site/ad:
"With no moving parts, the iPods new touch-sensitive scroll wheel is less vulnerable to dust, dirt or sand and more durable. The touch-sensitive scroll wheel is designed to retains its crisp feel throughout the lifespan of your iPod. Theres even a clicker that makes a tiny clicking sound when the scroll wheel is moving."
Eh? How, exactly, does it "move"? I liked the old system as it was, thank you very much. Is this like a rotating touchpad?
