er.. even i am not sure .. but as far as i know it does not have nay extended storage? and yah the first generation were used as the external harddrive... and yeah it also requires a usb connection... you seem to know a lot about it Fron... great!
I have never heard of iPod with expandable storage.I have a fifth generation iPod and it doesn't support this feature.
But the idea sounds great.The question is how it will be implemented. But surely it will provide great flexibility once it is done.
