I'm considering upgrading from my iPad 3rd gen. to an iPad 4th gen. I would get some performance boost while still being able to use my favorite case, plus subsidize the cost of the upgrade by selling my 3rd gen. If I get an Air 2, I won't want to sell the iPad 3 because I won't have one from that era, I don't mind selling the 3, if I get a 4th gen. Same exterior more or less besides lightning. How were the screens on the 4th gen? Better than all the Air 2s I read about? My 3rd gen looked great. Being a sealed eBay unit probably, I won't be able to be picky about the screen. Thanks.
