It looks like my accelerometer is off by almost 2 degrees on the long edge. I played both xplane and asphalt 8 the plane/car veered to the right when holding it level on a desk. 7.0.3 fixed the issue with the iphone 5s but not sure why the air is way off. The short side seems level and back is about 1.5 off. It's more of a shame with the ipad as I'm more likely to use it for games. Whats interesting is the bottom and left side are perfectly level it the top and right side that are off 2 degrees. As long as I don't use it on those 2 sides it fine. Unfortunately its a little harder to test for most people as you have to download apps.
