Anyone have any experience with these cases, or any thin/minimalist type cases? I am not looking for drop protection, just looking to avoid unnecessary scratches. I curious about: Full coverage (bottom covered) vs exposed bottom. Does the original Apple charger & headphone fit properly or should I opt for an open bottom case? Grip Any of them offer a better grip? Scratches/Smudges Do you notice any scratches or smudges on the case? Thanks for any feedback.
