Gorilla Glass 2: your designs can take on a whole level of strength.

Last night I got home and it was Christmas, a bright shinny package was sitting on my front door. It was from Verizon, my new Galaxy S3. This thing is really pretty compared to my old Motorola Android 1. Ok, shorten the story Bob. I need a case? I don’t think so because besides the 4.8 in screen and dual core processor this thing has Gorilla Glass Version 2. This phone is one of the first products to show off this extremely strong and scratch resistant alkalialuminosilicate(big word) material. But don’t take my word for it; check out the material properties and video from Corning.
