I agree with some of the comments already here...they definitely need more work. I can't quite place my finger on it, but something just doesn't look right about them. Also, I can tell you from experience...I'm sitting on 3 different companies prototypes of all aluminum cases that have a "closed back" (the back of the case is completely covered in aluminum), that in almost all scenarios, it will drastically affect the GPS reception abilities of the phone. ExoVault, Xcel technologies, Fusionwerkz, and one other company's prototypes that I've dealt with have all had fully enclosed backs, and each one would knock out the GPS reception completely, or make it so that its tracking was very unreliable. And each of those companies now acknowledge that, or have completely changed their designs to some form of an open back. So keep that in mind when "designing" these cases.
