> Tile floors are far more likely to result in a smashed device than any other type of floor, including concrete, so it's not surprising that there's a difference here. My theory is that a counter-top or kitchen floor is more likely to have debris on it, generating a pressure point on the glass and causing it to crack. I've dropped my 4S on flat surfaces (bricks, concrete) with no real issues. I dropped my old 4 two weeks in on the pavement, on a tiny rock, and the back shattered (Apple fixed it for free; otherwise it was AUD$39).
