My husband bought me an Ipod Nano for my birthday last year and I love it. Mine is a girlie purple and I find it holds everything I want to listen to in a day.
It's easy to use, the screen is a good size to see and even watching movies on the screen isn't bad for its size. I mostly listen to mine in the car but the supermarket and running is good too. Because of its small size it means you can fit it into your pocket no problem, better than I fit my phone!
I have a cover on mine as I'm quite clumsy and do just dump it in my handbag and haven't had any problems. I would recommend to others to get one for their ease of use, light-weight and its generally brilliance. However, I love Apple products so I think everything they have is great!
