There are some pros and cons when you compare the latest Classic to the latest Nano. Maybe this can help you decide.
Pros Nano:
- Handier, smaller, lighter
- No moving parts, so smaller chance things will break.
- More beautiful (just my opinion)
- Video camera
- FM Radio
- VoiceOver which can tell you what album/song you are playing
Also Nike+ and built in pedometer.
Which tbf it doesn't sound like you'll be all that interested in using.
