I love my new MP3 player! It has the ability to bookmark, which allows me to pick up right where I left off when I turn it on. I haven't used it for music yet, so I'm not sure how it will be, but can't imagine it would be anything but wonderful. The sound is great from such a small device, but I'm using different headphones than the ones which came with it. I recommend it highly and would have given it a 5 star but for the little plastic cover over the port where you plug in the USB cord. It doesn't go back in very well.
