Apple has redesigned its iPod nano to feature the Multi-Touch interface which lets you browse your music collection by swiping a finger on the display.

The new model is nearly half the size and weight of the previous generation and features a polished aluminium and glass enclosure with a built-in clip. It also comes with 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 will be available next week for $249 for the 8GB model and $299 for the 16GB model.

Both models are available in silver, graphite, blue, green, orange, red and pink.

Staying with the iPod family, Apple also announced a redesigned iPod shuffle that features both clickable “ring” buttons and Apple’s VoiceOver technology, which allows users to navigate their music and playlists without even looking at the device if you so wish.

“We’re making the iPod shuffle even better by combining clickable buttons and VoiceOver technology, so users can find and enjoy their music without ever looking at their iPod shuffle,” said Steve Jobs, Apple’s CEO. “With its all-aluminium enclosure and built-in clip the new iPod shuffle is a great workout companion, and at just NZD$89 it’s a great entry-level iPod that almost everyone can afford.”

The fourth generation iPod shuffle goes on sale next week for $89 for a 2GB model in silver, blue, green, orange and pink.
