The iPod Nano 7th generation has just been released, people are receiving the device out of the box in OS version 1.0 but, after Apple already loaded the iPod Nano 7th gens with the 1.0 version they shortly released an update to 1.0.1. This update is due to the fact that the new iPod Nano is not properly compatible with the newest versions of iTunes. Typically they update iTunes and then release the devices but, because they did not this time, they have to push an update to the devices to allow them to properly work with the newest versions of iTunes.

If you have an iPod Nano 7th gen or will shortly be receiving one, be sure to plug it into iTunes and update before you use it.
