Broken Iphone Screens

People if you had $700 or $200 in your pocket to pay for Iphone are you really that lazy to buy Iphone Case? Or is it just that it cost too much for you? I was currious how many people break their iphone screens, easy enough flickr shows me A LOT. But then I ask my self how is that possible? I dropped my Iphone and Ipod Touch numerous times but thanks god nothing really happen because I have iphone and ipod touch in my case 24/7.
