I've had my Iriver for about a week, and am rather pleased.Here are the only problems I'm having with it:-Poor bass boost. The CD player I used before buying this had amazing bass boost, and the Iriver is mediocre in this category (and its not just the headphones)-Sorting. One thing Itunes does that the Iriver does not do is combining files (for example) by "Beatles" and "The Beatles" I had to go through and rename them each after I'd put them on the Iriver, mildly annoying.-It only works on Windows XP, which was fine for me. But I would be annoyed if I had to go out and get it just for my mp3 player.Thats about it. I love the screen, all the extra goodies (radio, voice recorder, picture file, etc.)I reccomend this mp3 player.
