I'm a proud user of an old-fashioned, low-tech mobile phone. So I'm bemused by the shockingly large array of smartphone add-ons launched at a technology fair this week.
One add-on can deliver a 650,000 volt stun charge. I'd be scared if people were carrying around something like that in their coat pockets.
I think it takes technology a step too far. I often wish people would turn their phones off and pay more attention to the world around them.
