Apple’s iPod nano saw the most radical redesign of all the iPods announced today. The revolutionary click wheel has been removed in favor of multitouch screen and it is half the size and weight of previous generation. The iPod nano is truly nano now. It features a polished aluminum and glass enclosure with a built-in clip, making it instantly wearable. The new iPod nano features Genius Mixes, the ability to create and edit playlists, a built-in FM radio with live pause and up to 24 hours of music playback on a single battery charge.

“This is the biggest reinvention of the iPod nano since its debut in 2005, and we think users are going to love it,” said Steve Jobs, Apple’s CEO. “Replacing the click wheel with our Multi-Touch interface has enabled us to shrink the iPod nano into an amazingly small design that is instantly wearable with its built-in clip.”

The new iPod nano with Apple’s Multi-Touch interface allows users to access their songs, artists, albums and playlists with a tap or swipe of their finger on the display. Holding down a finger returns the user to the Home screen, and users can easily use two fingers to rotate the screen if it is clipped onto their clothing upside down. Users can also customize their Home screen by simply dragging icons from other screens onto the Home screen.

iPod nano also features Shake to Shuffle, giving music lovers the ability to shake their iPod nano to shuffle to a new song in their music library. It also features a built-in pedometer that makes it easy to track your steps and also supports Nike + iPod, giving users the ability to track runs and workouts.

The new iPod nano will be available next week for a suggested price of $149 for the 8GB model and $179 for the 16GB model. Both models are available in silver, graphite, blue, green, orange and pink. You can pre-order the new iPod nano
