At today's Apple event, Phil Schiller introduced the updated iPod nano. It's got a multi-touch display that's easier to navigate than last year's model, with a much-improved fitness experienced. Also, as an answer to the watch band accessories out there, Apple's added 16 new clock faces to make the nano more watch-like. They're available in seven colors, and are available today--8 GB for $129, 16 GB for $149.
