Glass breaks, sky is blue, water is squishy... whats new? You do realize that every phone has glass that comes to the edge right? Just because the lcd now goes to the edge all the way around doesn't mean its any weaker, the lcd is simply glued to the glass, doesn't matter if its 5mm from the edge or 1mm from the edge. If the metal frame inside is weak and it deforms when dropped the glass will break.
I have a feeling apple will use this in their next iphone, sharp will be providing them with oleds next year.
