The M-Edge team flagged me down today as I was passing their booth.They wanted to make sure I knew about their newest case offering. In the not too distant future they plan to offer customized cases. There's only going to be 1 case offered, and only the iPad, Nook, K2, and K3 will have this option. Cost is expected to be $40 for the Nook and Kindles and $50 for the iPad. They'll also offer some semi-custom designs from the designer Out of Print as well as other designers.
As you can see from the next photo, you can create a design for both the from and the back of your case.
