I mean, not disagreeing with previous comments in regards to scratching of the mentioned glass, but they are clearly saying nothing about scratch-resistance but instead about being tougher for multiple and repetitive (!) drops. I would rather have a rare small scratch here and there than a completely shattered glass. ¯\_(ツ)_/¯
Corning has announced Gorilla Glass Ceramic 2, a new, tougher glass for use in smartphones. The durable glass can survive repeated drops from 3.3 feet (1.0 meter) onto concrete.
