It depends on the materials used, I have a black 4S (and love it), but chosen a white iPad mini due to the fact that the black it is anodized aluminum. I consider to upgrade to iPhone 5S, would then choose white if it still uses anodized aluminum. I bought the new iPod nano recently, in silver, based on the same fact as well. I would love to see a black front (covered under the touch-glass in combination with a silver back.
