I think iPod Nano's small screen looks better and more usable with square icons. Your thumb will completely cover the small round icons while using the new iPod Nano so you won't be able see if the icon is pressed or not, but with the square tiles you can see the corners of the icons and see the touch animation.

What do you think?
