I have always been reluctant about buying an I-Pod, due to the fact I HAVE to use I-Tunes to transfer mp3's to it, however I wish I had taken the plunge sooner because the I-Pod nano is BRILLIANT.
It has the ability to play not only mp3's (songs) but also mp4's (Movies) and you can also have photo's on there. Its so small you barely even notice that you are carrying it and the black version that I have is VERY sleek and stylish. The earbuds are just about right, I have heard a lot of complaints about them but to be fair they do the job well! The menu system and the click wheel for navigation is very easy to use and id picked it up with in minutes.
With the Ipod Touch coming out this is a great chance to get yourself a bargain with the I-Pod Nano being so cheap! As I said earlier the only downside is that you HAVE to use I-Tunes to manage your library, this I have found to be very annoyinng with the interface not really being that easy to use, but other than that it is excellent!
