This makes no sense.
If the ipad Air was 1 and the case was 1.2, the total thickness is 1.2.
If the Air 2 is 0.8 and the case is 1.2, the total thickness is 1.2.
No, I was talking about the thickness of the casing, not the thickness of the case when closed.
That is, iPad Air is 1, the case would add .2 thickness, so the total would be 1.2.
Air 2 is .8, the case would add .2, so the total would be 1.0.
But never mind all that. I looked up the actual dimensions of the Air1 and Air2. Air 1 is 0.29 inches thick. Air2 is 0.24 inches.
That's a difference of 0.05 inches. Not 0.5, 0.05!
Do you have a ruler that can measure that difference? I don't.
Those of you who were expecting to be able to see a significant difference in thickness between the Air1 and Air2 have been taken in by Apple marketing. 0.05 inches is within expected variance for leather cases of this type. Of course we can't tell the difference in thickness between Air1 and Air2 cases, it's stupid of us to expect a difference in the first place.
