To the muggers it's all about return of investment. If everyone carries cash, muggers will find more people with cash and find it worth the risk. If no-one carried cash, they'd probably give up and try to steal bank card details from large retailers instead. The same goes for smartphones and tablets. If they are easy to sell on after stealing, crime will go up. Making the items useless if stolen removes the incentive. http://appleinsider.com/articles/13/05/02/nyt-article-accuses-apple-of-not-doing-enough-to-prevent-iphone-thefts http://appleinsider.com/articles/13/05/02/nyt-article-accuse...
