Looking for recommendations for a case with a built in screen protector for my iPad 3. I would prefer not to use one of those screen protectors that you periodically have to replace. I have had them before for iPhones and have not been very happy with them. I was all set to happily buy a Otterbox, but have read such negative reviews re: distoration of the beautiful retina display that I am reconsidering having a built in screen protector type case and just going with more of a folio style that flaps over. Has anyone found that perfect case that protects the iPad 3 screen yet doesn't diminish the quality of the screen? Thanks for your help!
