This is the first time I'm actually considering getting Apple Care+
Wife and I never had any issues with any of our Iphones or Ipads but seeing how OS dependendant these new devices are and how buggy they are even when released, for peace of mind I'm thinking of getting it for the 11Pro.
Interface and FaceID seems to be fast again on the 11Pro vs the X, however I'm still noticing some black screens on the camera app, mostly when switching from photo to portrait mode.
