Query: Great sound - a lot of features

Very elegant solution for portable MP3 player and USB2 memory stick.Flash memory is much better for MP3 players than HD based devices if you plan to walk or run with it. I had a 20GB player and the HD died afte running with is few times. 1GB is more than enough.The sound is excellent - quality and volume.Radio, equalizer and recorder all function on one AAA battery.Great product!
