ok, um stop talking about scratches and stuff. It doesn't matter what brand of MP3 player you have, if you take care of it, like you should, it will look good after years of use. There are also these skins you can buy for any brand of MP3 player. It's a polymer sheet coating made by 3M. Totally clear, very thin, but you could seriously stab it with a knife over and over and the scratch on the skin will brush right off, and it will still look just like new.
As far as the interface goes. How much more straight forward can you get than the iPods interface. I mean......I've never seen anyone stare at an iPod and say "I can't figure out how to work this thing."
