I have a retina iPad (version 3) and since 2 months regularly I've got a full white screen when I turn it on and I have to make some voodoo incantations in order to make it disappear. So finally I sent it to Apple and they returned me without any repair after having concluded they could not reproduce this issue. So now I'm back with an iPad that is not working correctly half of the time. I'm disappointed at Apple, I'm not mad, I'm just disappointed. I'd live near an Apple store I'd brought the iPad to show them the issue but it's not the case.
