I recently cancelled my order with Dell for the Ipod 30 Gb model. I contacted Apple and inquired what it would cost to change out the battery and he said it would be $159.00 plus the owner must pay shipping both ways, which amounts to another $40 making a grand total of $200 to change the battery approximately every 2-3 years. You can purchase a battery from Ipod Battery for $59 but it requires some disassembly which could damage the unit. The unit would be perfect with a piggyback battery unit.
