Cheap Apple iPod Store

The samsung epic is $50 more then the htc evo 4g. whats the difference? do the phones have the same features, or does the epic have more features that the evo dosent.

When i was trying to place music on my ipod for the first time (on a window computer) it told me that: in needed to restore and update my ipod to make it a “windows ipod” because it was a “macintosh ipod”. Whatever that means. So, whats the difference?
