Re: bad breath ?
Actually, the phone probably has more novelty value than real use, but I did read the Siemens are looking at using the technology elsewhere. Possibly in Cars. It would be good if they could design a reliable device that prevents cars starting if the driver is drunk. By reliable, I mean a device that doesn't just disable the engine if there is the slightest whiff of alcohol on any of the passengers.
Obviously, certain people would find a way around it, but I suspect such a device would cut drunk driving incidents down.
