I bought my iPod nano a couple of months ago after going through a number of unsuccessful mp3's, and now I only wish i had bought this first to save me the money!
The amount of things it can do is great and extremely useful, especially considering its size.
Its not too heavy, but not too light, and has a big enough screen to be able to enjoy any movies or shows you might happen to put on it.
It plays most of my songs, making it especially useful on my paper round every morning, ensuring i dont get bored, and even sometimes at school.
You can take it anywhere you go and view pictures, play music and watch tv shows and movies. Its size ensures that you can take it almost anywhere without any hassle.
Sometimes I can't believe i done without before!
Its a definite must have for fans of music, those who travel a lot, and everyone in between.
