Of iPods and nanoPods

iPod, uPod everyboody PodPod. Every decade there is a surprise innovation that just takes off. In the nineties it was the mobile phone and er, the internet. Ok, every decade there are two innovations that take off. In the noughties it is the iPod and er, something else probably. An iPod would be no good without iTunes and now there is an iPod nano and an iPod mini and an iPod video, or is that nanoPod, videoPod and miniPod? There is definitely an iPod shuffle coz I saw one on the train. These things store so many iSongs that you could listen to them for the whole lifetime of the observable universe without repeating one twice. That is probably all you need to know, except that it has USB through Dock connector and now you can get an iDog.
