To anyone using the Smart Cover with his or her iPad: has the Smart Cover damaged your iPad (like [light] scratches)? I will most likely upgrade to the iPad 3 (as long as it is a good upgrade) from my iPad 1, so now I'm wondering if I should buy the Smart Cover. It's got real functionality and I really like the fact that the iPad isn't "wrapped up" in a case. I'm assuming the iPad 3 will still have some support for the Smart Cover. In fact, I only put my iPad in [Apple's original] case, when I'm taking it abroad or somewhere far from home. Three questions: - Does the Smart Cover scratch your iPad (left side)? - How protective is the Smart Cover? - How useful has the Smart Cover turned out to be for you? Do you still use it as you planned to use it? Or is it more as a "gimmick"?
