I took some quick pictures of my nano compared to my 60gb photo and my 15" powerbook in case anyone needs more reference for their size. All of the pictures can be seen here: Link or go too: http://homepage.mac.com/jimbo0270/PhotoAlbum17.html The picture next to the powerbook lid is a little deceptive.. the Nano is actually a little thinner than the lid. Also, a little info: It will not sync up using the old firewire cable. I cannot use the auto fill feature to work from a smart playlist.. if there is a way to do this please let me know. The battery seems to last quite a bit longer than on my 60gb but I have not done a real time test. . Oh, and it looks so good in my car (black interior) I think I am going to make a dash mount for it.
