Apple has unveiled the latest version of its iPod Nano, featuring what it says are the thinnest measurements yet.
The fourth generation Nano was launched at a US press conference by Apple chief Steve Jobs, who announced new shuffle and library features.
He also listed the Nano's environmental credentials, including arsenic-free glass and a mercury and PVC-free body that is "highly recyclable".
The Nanos are expected to sell in the UK for £109 ($191) for the 8GB version.
The 16GB version will retail at £149.

Apple CEO Steve Jobs
Speaking live in San Francisco, Mr Jobs unveiled Apple's new Genius function which allows users to create automatic playlists from the iPod's library with the click of a button.
He said the function worked by taking one song and creating a playlist based on the user's song library and could also suggest other tracks the user might want to buy.
Mr Jobs said the new Nano also had a "shake to shuffle" mode, which sends the gadget to shuffle mode with the flick of a wrist.
'Lots of fun'
The Apple chief executive officer said the company had sold more than 160 million iPods since its introduction seven years ago.
An updated iPod Touch - the closest cousin to the iPhone - was also announced at the event.
It is thinner than previous models and has integrated volume controls and a built-in speaker for "casual listening" and will also include the Genius function.
New software for the iPhone - which will be available free to all users - would "fix a lot of bugs" including dropped calls and connection problems reported by customers.
Mr Jobs said: "We're really, really excited about all these products. We think people are going to have a lot of fun."
