You can also stick a regular CF flash card in your iPod mini...less songs, but probably adds battery life. Remember the myth of the $100 profitable iPod? It's pretty obvious that Apple loses money on the hardware (not that there's anything wrong with that). EDIT: Disclaimer: Some people say it doesn't work, that the drives are locked in IDE mode. Others say it does if you format the drive correctly. Perhaps both are true; some drives locked, some not.
