Where I work I see people go through cell phones like shit through a goose. I haven't figured out what proportion is caused by idiots that throw their cell phones at their girlfriend in the middle of a fight or run over them with their car and expect me to be able to fix it and what proportion is caused by companies just making flat out cheap ass phones that self destruct whenever someone breathes on them wrong. (I'm not kidding about the guy that ran over his phone with his truck and brought it back and wanted me to repair it. That really happened.)
