I've had a Moshi case on every MP3 player, Apple or other, for years. I even have the first version (with the metal toggle and no wire keeper on the back), which is still keeping my old MP3 player safe, for over 4 years now! This case means you can keep the iPhone au naturale - no case, no screen protector, NOTHING. Just slip it out, and use it the way it was intended to be used.
Here's the bottom line - everyone is always shocked when they see my iPhone without a case strapped to it, and amazed that it's always shiny, with not a spec of dust, fingerprints, and no scratches. It looks like it's brand new all the time - and the secret is the Moshi. I can't express enough how soft, versatile, and durable the iPouch is. I lost mine somewhere over the weekend, and couldn't jump on here quick enough to order a replacement.
