My MacBook fell out of my car and fell straight into concrete cement. Very small scuff and she still works, no damage to screen. I have a time machine backup should anything happen to the hard drive. Which is funny, this beat my ThinkPad which has a piece broken off when it fell onto concrete for the same reason. And ThinkPads were known for their durability. How this happened was funny, it was simply because I had the computers leaned up against the car door...and I opened the door. Definitely more durable than any PC I have owned.
