As someone you know that has a shuffle, I suggest you get it as well. Why? The nano is more fragile. Without the proper enclosure, you may damage the screen and it may become a shuffle itself (Get it? iPod without the screen? Never mind...) Another reason why: That mod was made with a shuffle, not for a nano, and your nano may be a bit too big to fit in the headphones without damaging them further. Also, what's the point of getting a nano when you already have an iPod with a screen? I got a shuffle because I hate carrying around my 20GB iPod in my pocket (huge bulge). The shuffle doesn't take up much room, and yes, it would be the same with the nano, but you still gotta watch out for that screen.
