My wife is thrilled with the PRS-600 I got her for her birthday (self-defense, she had glommed onto my Pocket and refused to release it). She is especially thrilled with the music feature. However, most of her favorite tracks are in iTunes. The docs say the Sony will play unprotected AAC, which should be most of current iTunes tracks, but not the older stuff. Is there any convenient way to tell the difference?
