I love my 4G Touch, but I worry that I might squish it. It is so thin. When traveling, I usually carry my iPod in a pouch in my backpack. There are usually a few heavy books in the bag as well. Now, it is seems possible for the weight of the books to bear on the iPod in such a way that it damages it. It might seem far-fetched, but I've incapacitated a Garmin GPS unit in this way. So, I'm looking for something that'd provide some sort of protection against this. I'm mostly worried about the glass screen, as it seems like it'd be the weakest link here. I suppose I'm not after a case, per se, more of a protective shell or tote bag. Anybody know of anything good? Plan B is to use the case that the iPod came in. But I'm not sure if it will fit after I put a Grip Vue on it.
