Not melted, but I had a rather expensive idiot moment a few weeks ago. What's worse, people pre-warned me.
A few months ago, I bought a new phone. Because I'm not one to generally drop things and the phone usually lives in my bag, I didn't bother getting a protective case for it. I was told by family members I should have a case and even had offers to buy me one, of course I knew better.
As I was carrying boxes to the car (with my nice new shiny glass phone resting on top), it slid off, straight onto the concrete garage floor. The screen didn't stand a chance and shattered entirely. After a trip to the Samsung store and $300-odd dollars later, I now have a case for my phone :-)
