Just how fragile is the Samsung Galaxy S3!?

Hey everyone, I recently received the S3 on Thursday, and two days later, it broke, from falling from a height of around 1.5 ft. I've been browsing the web and have learned that many other users' screens have cracked from dropping at relatively low heights.

What's wrong with Gorilla Glass 2?

I for one am very frustrated, now it will take me [who knows how long] until my phone returns from the Samsung repair facility. Ugh.
