Kudos to that thoughtful commuter that shut off that woman's  
conversation!  It's even worse with bluetooth devices!  In the  
bookshop or library, it often looks like some idiot babbling to  
himself, and loudly at that!  I've often thought the person speaking  
to me till you see the cyberborg device hanging from their ear.

I'm all for new technology, but I think in many cases we've regressed  
by having to be on a phone nearly 24 hours a day.  Neighbours of mine  
can't even exit their house without immediately getting on the phone.

I'll have to investigate a schematic for one of these jammer devices -  
for educational purposes only, mind you.
