Mike Flaminio of Insanely Great Mac has found a bit of a flaw in both the polyurethane and leather smart covers for the iPad 2. After a bit of use on the iPad 2, the oils from his hands were being picked up by the smart cover from the display. Upon lifting the cover off, he found that the smart cover was leaving marks and smudges on the iPad. They aren't permanent, but still require maintenance. Mike demonstrates the entire process in the video embedded after the break.
