We have the original iPad with the original Apple case, but skipped the iPad 2 and don't know anything about the smart cover. From what I can tell, it protects the screen, and functions as a stand, but doesn't do anything to protect the back of the iPad. Is that right? Can anyone recommend a good case to protect the entire iPad, not just the screen? I am interested in something that will hold up to use by a 9 year-old who might forget to be careful with it. Alternatively, are there covers for the back that can be used in conjunction with the smart cover?
