Ok, I'm thinking about possibly purchasing an iPod. The Nano is very interesting to me because of it's size and lack of a mechanical hard drive. Additionally, I don't really need 30GB of space in the foreseeable future, so 4GB should be fine for me. HOWEVER, I know that when the Nano's first came out there were reports of them being scratched very easily. I'm a little worried about how fragile the Nano seems and think I might prefer the "bulk" (for lack of a better word) of the regular iPod. Could anyone share their experiences with these two devices and their preferences? I would also like to hear about battery life on these newer models.
