After 300 million iPods sold, Apple isn't slowing down. They're announcing a new iPod nano today. It's a mere refresh of last year's model, with a new UI of swiping through apps (instead of a grid), and new built-in run tracking capabilities (no Nike+ required). More importantly, however, Apple has added sixteen new clock faces for all the folks who've been turning the nano into a watch. The 8GB nano is $129 and the 16GB version is $149; they're both available today.
