For the regular (large) iPad, there is an Apple Smart Case that is entirely polyurethane with a soft shell cover. I am trying to find like that for the iPad mini. Was there a polyurethane Smart Case for iPad Mini ever released for the 1st generation iPad Mini (that I can also use for 2nd generation iPad Mini)? The current iPad Mini Smart Case (unlike Smart Cover) has no polyurethane option, and the back shell is hard. Anyone help?
