I got a black 4Gb. I like it. I would highly recommend getting an Invisible Shield (although its stupid you have to). I don't have any scratches on mine because of it. I get around 14-16 hours of playing time on mine, so it sounds like there's something is wrong with yours.
My nano 2g white has only 4-5 hours of battery life... its supposed to be 14.
The screen is easy to scratch, and the sound is TERRIBLE.
Am I the only one who is getting these problems?
