This nano has had some vast improvements from the first generation all those years back. The screen has enlarged, and is very good. The colours and clarity is exceptional for something this small. It is a lot thinner, less than 1cm, and has a nice curved shape. It has a new feature not before seen on the nano, let alone any ipod, and this is a shaking the ipod to change track. The genius software is very good and I find very useful and selects suitable matches for my music library. Also, new with this generation is the accelerometer built in. This allows you to turn the ipod on its side to watch video. The price is very good, but is still expensive for its capacity. However, this is made up for in superb free software that is very easy to use and master. Also, this is by far, the most accessory orrientated MP3/4 player. However saying this; some of the new generation ipods including this one don't work on old docking stations. You may want to be aware of this if you intend to use old accesories.
