That's why I've bought Otterbox cases for all my devices at the same time or slightly before I got them. WHen I was working at a wireless ISP I dropped my phone about 40 feet onto the pavement, not a scratch and the phone wokred fine for another 2 years (new job, gave me a phone so my old cell was redundant).
On the other hand this report is kinda misleading... when I read "Half of All Active Phones are Broken" I was assuming broken = cracked/shattered screens and other major breakages. Scratches to the body mean absolutely nothing to performance, shattered screens however....
