My son bought an iPod 4 months ago for over $400...
Was the iPod new? Even a 20GB model runs around $440 at retail, and with tax, that's around $500.
If he got it for closer to $400, I'm guessing it was used or something. . . was it a product return? If so, take it back to where you bought it.
That's the main failing of the iPods - the built-in battery, while great, is like any other Li-ion battery, and after 300-400 charge cycles, it's done. So, if a person fully charges it every night, it's most likely going to have some battery issues after a year.
