It is a multimedia storage device, it has a very user friendly and simple interface. It stores music, photos, videos and eBooks. There are a few games available for it. It has a scroll wheel which when you move your thumb clock wise over it it will scroll down the screen and counter-clock wise it will scroll up. The new iPod Nano comes in 4GB and 8GB version. It is meant more to hold a video or two and some music. If you really like Videos then you should get an iPod classic which comes in 80GB and 160GB it is meant to store your movie collection.There is also the iPod shuffle which has no screen and people usually get that if they just need to work out i believe they come in 512MB and 1GB Then there is the iPod touch which has a touch screen and operates like an iPhone without the phone capability. iPod are popular because they are very thin, come in different versions to suit your needs and very colourful along with a very nice user interface. Hope this helps
