I'm finally entering the 21st century and I'm getting an iPod (hey, I got DSL last week, so I'm progressing by leaps and bounds

). I'm trying to decide which Ipod to get. I'm stuck between the Ipod Classic or the Ipod Nano, and the size (how many gigabytes?). I have about 3100 songs in my current iTunes (conversions from my CD collection). I'm anticipating that I will have more uses for the iPod as I use it more. I would love to hear from other dancers regarding features they like and other features/uses they didn't anticipate they would use but they really enjoy. I would love to hear your input.
Cheers, and thanks,
Rose
