I have the cover that came with it. However, I would prefer to have one that is still slim (not leather because it isn't slim enough), but covers the entire iPad AND gives me the ability to hide a few folded letter-size pieces of paper behind it. Slim is had to find when it comes to aftermarket so your help in this endeavor is greatly appreciated.
criteria 1. slim
criteria 2. covers the entire ipad (except for buttons and camera)
criteria 3. need to be able to tuck some folded paper behind it
criteria 4. pen holder (not required but nice to have)
