like the title says, i need a new ipod for the car. my 2gb just isnt cutting it anymore. I have enough points on my Credit card to get a new ipod nano but i see that the buyers guide says to hold off. what would be different about the new ones? just more space right? so if i wait i could get a 16gb for the price of a 8gb? when is the new one supposed to be coming out? anyone have any idea?
