Steve was right, the quality of the phone is like a Leica camera. It is glass and metal and just like a Leica camera, it will most likely break when you drop it due to the density. Everything is packed tightly. Build quality does not always equal durability. If this phone was to be super durable, it should have been made of rubber and plexi glass but then it would not be a pretty. Another problem is the glass on the back is very low friction. I sat mine on top of my wallet and it slowly kept sliding off. I read one guy scratched his back because it slid around on his dash board. With the bumper case it is very difficult to move and it raises the glass of the table to minimize scratches. It also makes it easier to grip and it keeps you from bridging the antenna. If this where a Leica camera you don't need a case because the way you use it you will most likely not drop it. This is a cell phone. You are pulling it out of your pocket or purse all day long. You rush to grab a call when it rings.
