...forgot to mention that my Exo came with 2 screen protectors, definitely a key item. My skin does not cover the buttons or scroll wheel, which I prefer.
I think Lajo was the original creator of the iSkin, but apparently broke away from his business partners and had a subsequent legal battle over the design, product name/patent etc, and he's now on his own. He was actually banned from one of the message boards (ipodlounge I think) for too many promotional postings, so I'm not a big fan of the guy when it comes to his business ethics, but I've been pleased with the product.
Check out the iPod Art skins at his web site!
