Martin Hajek has created some nice renders of the expected iPad mini for Gizmodo.

It would be a nice surprise for the rumored imminent presentation of the new 7.85-inch model: iPad Minis with anodized aluminum backs in different colors, just like the iPod touch. It’s pure speculation, but it kind of makes sense. The color backs would make the cheaper iPad mini quite different from the Kindle Fires and the rest of mini-tablets of this world. It’s playful and aligns with the iPod touch theme. And it would certainly help Apple sell gazillions of them this holiday season.
