I was concerned that the stainless steel band would be the scratch magnet it has been on the rear side of iPod models. But so far, so good. Been using the iPhone 4 with no case for the past few days now and there are no scratches whatsoever on it. It seems to take after the anodized aluminum of the iPod nano and MacBook Pro. I wonder if this new steel alloy will find its way onto future Apple products.
