I put mine in a Mobic battery case. The case was thick because it contained a second battery for the iPt4. Nice feel to the case and nice thickness. Unfortunately the battery in the case was as dysfunctional as the one in the iPt4 so I rarely got any extra battery life by using it. Personally I would like an iPod touch with a 5" retina screen and about a 3/8" to 1/2" thickness so that the battery would last for 8 hours. I'm not sure how a person with adult hands can even hold on to those tiny new gen 5s!
