I have the new Nano. I looked at other brands, and none offered exactly what I wanted - the Nano is perfect for me.
Since my first MP3 player, all I really wanted was a Shuffle with a screen. I don't need video, but I have too much music and I like listening by album, so the Shuffle would be frustrating to navigate.
My very first MP3 player was a Creative Zen. It was great until I broke it.
