I like the leather flip cases that fasten with a button (here's an example: http://www.amazon.com/GTMax-Permium...?ie=UTF8&s=electronics&qid=1283711996&sr=8-13 ), but since they don't have any of those out yet on Amazon that will fit the new 4g, I'm thinking of trying something new. I could go with silicone, but the cases made of TPU (here's an example: http://www.amazon.com/Shining-Prote...ie=UTF8&s=miscellaneous&qid=1283711024&sr=1-5) look a bit flashier and seem to be sturdier. Do they cause scuffing to the back of the iPod at all? This will probably be a temporary case for me, so small cons aren't a deal breaker. Opinions? Keep in mind that I do NOT want a hard plastic case. I've noticed they scuff the back of the iPod touch. I'm looking for one of rubbery material that is available for order NOW on Amazon (I can only order from Amazon at the moment, no other websites).
