There are so many versions of ipods, I could not even possible count them all. It seems like every time you turn around there is a new gadget out. Today I heard about a new version of the ipad that will add a camera to it and make thinner. Not to longer ago they came out with the 4 generation ipod touch and 6 generation ipod nano. Apple sure makes sure that you will not forget about them. It something that I have always said about electronics, if you wait long enough there will be a new and better version of the product in the blink of an eye.
