Chinese tech website M.I.C Gadget gets some amazing spy shots on occasion. This time, they have photos that purport to show the back case of the rumored iPad 3. As you can see from the photos above, the alleged iPad 3 case (bottom) is slightly thicker than the case of the iPad 2. Although the difference in thickness appears to be significant, another photo (below) shows that the iPad 3 case is actually only about 1 to 1.5 mm thicker.
