iPod nano fourth generation review :
When we are one of the podville 3thgeneration, may be the only storage capacity up to 8gigabyte. This is not going to happen if we see this product. We can upgrade to 16gb. iPod are popularize this design is small and lightweight. The lack of this product is the battery capacity must be increased again.
