Good and bad here and I can't decide which side I'm on. When apple did this they SEVERELY reduced the theft of iphones. And while no one wants their phone stolen in any way, it's the muggings in large cities that really went way down. People saw those white iphones cords going into people's pocket and they new an expensive, desirable and easy to sell phone was at the end of it. I've never been mugged, nor have had a family member, but the idea of someone stopping my wife or kid on the street demanding their phone terrifies me.
On the other hand, I work in corporate IT. I've seen the stack and stacks of iphones and ipads that have been locked by the user and we can't reset them. For whatever reason our predecessor didn't lock down icloud with the MDM, so the users logged into icloud. We told them when they quit they had to remove it, but many didn't know how and they just shipped us their locked phone. Holding their last paycheck is illegal, so we ended up with stacks of expensive, shiny and useless hardware. I even brought about 5 ipads home because I was going to see what sort of 'hacking tools' I could use to unlock them. Haven't gotten around to trying yet.
