Apple this morning added a twist to its iPod shuffle range, introducing four new coloured models of the diminutive device.

The move means iPod shuffle's are now available in blue, pink, green, orange and the original silver.

"iPod shuffle is the world's most wearable digital music player," said Greg Joswiak, Apple's vice president of Worldwide iPod Product Marketing. "Music fans can now choose iPod shuffle in one of five brilliant colours, or they can buy one of each."

The 1GB flash-based iPod shuffle is half a cubic inch in volume, weighs half an ounce and carries a built-in clip. It offers up to 12 hours of battery life. The price remains the same: £55, including VAT.

The device requires a Mac with a USB 2.0 port and Mac OS X 10.3.9 or later and iTunes 7.0.2 or later; or a Windows PC with a USB 2.0 port and Windows 2000 (Service Pack 4), Windows XP Home or Professional (Service Pack 2) and iTunes 7.0.2 or later.
