The world's smallest music player just got smaller — and smarter. About half the size of the previous model, the all-new 4GB iPod Shuffle ($79) features VoiceOver technology, which enables the Shuffle to speak your song titles, artists and playlist names. Screen? Who needs a screen? The new Shuffle is wrapped in an awesome new aluminum case in silver or black, and sports a built-in stainless steel clip for maximum wearability.
