About a couple of weeks ago I showed my brother my iPad as he was thinking of buying one himself. Anyway while he was looking at it my 4 year old niece had her face over the screen and her neckless was dangling on the screen. My brother gave her into trouble telling her that she could scratch the screen by doing that. Anyway I was meaning to check my iPad to see if the screen did scratch and just last night to my horror while cleaning the screen I seen a 1 cm long deep scratch mark. I don't know if it is coincidence but I'm wondering if the scratch was caused by my niece dangling her necklace two weeks before or if the scratch was caused by me carrying it all the time in a soft case in my backpack where I have wires and PSU adaptor in my backpack too. Surely the soft iPad case would protect the screen even with no screen protector.
