ok... my daughter wants an iPod nano for Christmas. I realize they are all pretty much the same price everywhere, but is there any "added features" (such as customer service, etc) by buying it from the apple store, or storeX, etc? Also... I've ripped all the CDs she has so that I could put them on the iRiver MP3 player that she has. They are 192kb/s MP3s. Will these files load on the nano without any type of conversion? If they need to be converted... to what format do they need to be? I've avoided the whole ipod fad until now, so I'm completely lacking in any knowledge related to the subject. Any help you can offer will be greatly appreciated. Thanks.
