I'm interested in buying a skin for my 15 GB iPod. I will have the skin on when the iPod is in my jacket, in my pocket at the gym, etc so I'm not concerned with a clip. Basically, I'm using it to protect the iPod from minor scratches, and want it to be thin as possible. I also have the remote and dock, and would love to be able to put the iPod in the dock without removing the skin, but this is not a deal breaker. My most important criteria is the size of the skin. I've been looking at the iSkin exo2 and the Speck iPod skin. I'm not sure what the size difference is between the two. Any suggestions out there?
