Does anyone have recent 2012 experience with using ipad2/3 or iphone4s outside with a good screen protector? I am looking for one that is: 1. Real screen protection 2. For use outside reading books, surfing the web 3. Does not show finger marks 4. Is user friendly to install 5. I've read old posts, loooking for 2012 experience I read about NuShield, Powersupport, and others - which is the best? Help?
