Security feature would be an attractive selling point
IT seems like a logical solution to a modern-day scourge: introduce a 'kill' switch on mobile phones so that even if they're stolen, the thief can't use it or sell it on.
What is a kill switch? It's a way of making your smartphone completely inoperable – after it's been stolen. The basic idea is that such a feature should be incorporated at source, by the manufacturer. That means by Apple, Samsung, BlackBerry (although it's hard to know who would steal one of those) and others.
The kill function could be remotely activated after the phone is lost or stolen, only to be reversed (according to some proposals) using the phone's original password.
