Okay, I've been doing research for the last couple of days on the Archos 404/504/604. All I want is a straight answer. Will it play the AAC files I ripped off of my cds and into iTunes? I know you have to download the pluggin, and I'm fine with that, as long as it will play the stuff. I'm looking at the 404 because of size, but if this will not do for playing AAC, which one do I need? Also, does it sync to iTunes? If not, not as big a deal. All I want is for it to play my AAC stuff, as this is the majority of my music.
