The bad stuff is probably the memory it holds, 32mb.
Now the Rio500 holds 64mb.
But then again you can add more memory to the Rio600, like the Rio500.
Overall I think it's a great Mp3 player. I give it a 4 out of 5 because of the memory it holds, but on all other qualities of it its a great mp3 player. Het I am getting on this Christmas, it sounds great!
