Cellphones and that annoying ringing

Just read a story today about a Kashmiri woman (that's Kashmir in India) who preferred her cellphone to her husband! If I have my facts right, she took exception to him taking exception to her always being on the cellphone and walked out. The miserable husband has now filed a missing persons complaint.
This just proves what I have long suspected - people are now impossible where their cellphones are concerned. If they aren't choosing ringtones on the train going home (now, why would you do that? Can't you wait till you get home), then they're refusing to turn them off during movies (and my message to them is - if you are so important that you can't sit though a two-hour movie without someone calling you and you NEEDING to take that call, then don't watch the movie). It's getting impossible, in India at least, to get people to turn off cellphones (at plays, during mass, for Christ's sake - pun intended) and at any occasion where it is polite to put the damn thing off (or at least in silent mode).
What is annoying, is that people simply refuse to understand that this is a matter of courtesy, politeness and good manners. I've also noticed that those with the fanciest phones (that in theory should come loaded with all kinds of silent modes and options where the phone doesn't need to ring) who can't seem to turn the damn thing off. And what really gets my goat is that now that having a fancy phone isn't even a status symbol (it was that in 1999, so people grow up), flashing it at all possible times is just so hick and nouveau riche.
One last rant - people who look at their cellphone for simply ages when it's ringing instead of actually picking it up!
