The iPod Nano, is a device from apple, that features an operating system similar to iOS that has many features. Of the many features there is: Music, Photos, FM radio, Clock, Pedometer, and the many features of iTunes.
The iPod Nano's music allows you to sync music from your iTunes Library to the Nano. That said, you can sync playlists, genius, artists, albums, and any songs.
The photos section allows you to sync (through iTunes) pictures from (on your Mac) from iPhoto, or Aperture (from your PC) or the photos folder.
The iPod Nano has a built in FM radio tuner, so your can tune in to any FM radio that you receive at a particular area.
The iPod Nano also has a built in Pedometer. This means that you don't have to bluetooth pair to a Nike+ shoe and chip. It tracks your workouts including the amount of steps, miles and more.
Recently, Apple accessory developers have been designing watch band cases for the Nano. Apple realized this, and integrated many many more clock faces.
This is my future watch.
