Most of your questions have been answered above so I will add a suggestion........get a case for it, if you don't want to splurge for the apple ones, go to Penneys they have a leather case made by Rolfs that it slides into, it also has a belt clip on it and a clip. Nanos are so small that they could easily be lost and if you have the black one they scratch very easily.......have fun with it, I couldn't live without mine or my mini!
