I guess I posted this in the wrong forum earlier! I've just turned on my iPad and I have a couple of inches of horrible squiggly pixels across the middle! I've not dropped it and it's been kept in a pretty robust leather case the whole time - however, I've just noticed a small dent in the aluminium on the back in the same place as the mess on the front. I have an appointment at the genius bar tomorrow but does anyone know what they might say? Will the dent mean that they won't replace it?
