Can we talk about this for a minute? Suppose a big guy or a group of guys see you walking in London in the dark and decide to do you violence. What is the main way a smartphone can help you in your opinion? By giving you a chance to get photos of them? By helping you get emergency medical help after they beat you up?

I'm genuinely curious, not just trying to score points.

Is there some danger other than violence from strangers that you think the smartphone will help you with?
