As we have observed, there are disturbing parallels between the ostracism of smokers and mobile phone users.
Although it's pretty much impossible to get by without a mobile these days, there's still an etiquette gap in their use. Some people seem happy to broadcast the most intimate details of their private life, much to the annoyance of others.
This combination of politeness and biting sarcasm appeals, but I'd think twice about handing out a slip if the source of the annoyance looks inclined to violence.
Alternatively, you can just become a Luddite although speaking personally you'll have to pry my mobile from my cold, dead fingers.
