iPod Shuffle's VoiceOver Solution
VoiceOver solution provides, a voice based menu to the iPod listeners. Solution looks quite great and you might end up thinking that iPod shuffle has TextToSpeech functionality. But answer is NO. iPod shuffle is still a device which can just play an audio file. The menu items come from the another audio-file which has been synced into your device thru PC.

Here is a patent from apple which is going to materialize the haptic feedback in real sense.
