Ok three questions regarding iPod: 1) Would it be wise to buy an iPod right now? Will Apple be updating the iPod anytime soon? 2) How long can a person expect the battary to last on the iPod on average? And when the battary does eventully go bad, I could take it to a local Apple store and have the battary replaced for $100, right? 3) iPod can be used as a portable hard drive right? I've heard people at my college say you have to set up iPod for hard drive usage. How hard is that to do? I appreciate any information you can provide. Thank you.
