It all depends on what your needs entail. The nano & shuffle have a small amount of storage which is ideal for those who have a small library, and they are extremely portable, ideal for the more active individual for use whilst running, exercising in the gymn, etc.. The iPod video, however, is better to suited to the 'tech/media-minded' of us. It offers a large colour screen, video playback, and a large hard drive storage (in either 30gb or 60gb). For info on prices & purchasing, have a look through the iPod section of Apple's site.. http://www.apple.com/ipod/ipod.html
