Twice from my windowsill, ~3 or 4 feet onto a hardwood floor, no damage or scratches. I also keep it in my pocket with occasional keys and /or change and its fine.
Approx 4ft drop. Landed on the pavement outside my office. All it did was chip that plastic lip that edges the glass back at the bottom right corner. Its fine really and I have to run my fingers along the edge carefully to even notice it.
