This leaked photo of what clearly appears to be the outer shell of a green iPod nano shows off a hole in the top right for a camera. Back in 2009, the 5th generation iPod nano (and the last one to feature a click wheel) added a camera but that was removed in the touchscreen iPod nano of 2010. It looks like the new models due out toward the end of this year might regain it. The problem is since the iPod nano is much smaller now, it's going to be pretty hard to attempt to take photos with it especially with a built-in clip on the back. In a device that small, I don't really see many benefits to having a camera at all.
