Continuing from my previous post: http://forums.macrumors.com/showthread.php?t=1168276 The skeleton frame is held to the mounting cover by 4 bumps, one in each corner, and 2 clips in the middle edges of the frame. Before fully clipping the frame to the skinned iPad: After: After covering the front of the iPad with the convertible cover. You can still see a tiny part of the Home button which isn't covered. The thickness of the iPad with the cover on is a little over an inch. There is a small gap between the cover and the surface of the iPad. I didn't try the Otterbox Defender or any other cases, so I can't compare this one to them; but overall, I really like this case and will be keeping it. I'll be using the iPad in an industrial environment, and this case looks to be pretty rugged.
