iPod Shuffle pays respect to its bigger siblings with a thumb-friendly, circular control pad that puts the "go" in ergonomic. Click the center button to play and pause, and click the outer buttons to move back, skip forward, and adjust the volume. The Shuffle's headphone jack does double-duty as a dock connector. Flip the iPod Shuffle upside-down and drop it into the included dock. Then connect the dock to your Mac or Windows PC via the USB for a quick sync and charge. And if you're away from your computer, you can charge on the go with the optional USB adapter.
