iPod nano

Believe Your Ears
Take everything you love about iPod and shrink it. Now shrink it again. With 2GB (500 songs) and 4GB (1,000 songs) models starting at $199, the pencil-thin iPod nano packs the entire iPod experience into an impossibly small design. So small, it will take your music places you never dreamed of.
