There's a plan to allow mobile phone use on the London underground.
But not everyone is happy about the idea.
Apart from security worries (bombs can be triggered by remote control, of course) there is the fear that people will be driven to phone rage by the sound of "I'm on the train..." and the subsequent tedious personal conversations.
I have a solution. Just allow data calls.
Then people can blog away happily and we'll really see where this technology is going!
