I can't help but reply once more...
Just like with many other things in this world we live in, let people purchase whatever the %#%^ they want with their money. People here complain about others driving SUVs but not minivans and pickups for christ's sake. I don't see anyone complaining about the guy driving a Porsche on the highway with the 60mph speed limit. Think about it.
We have special freedom and privileges that many people in the world don't (and I'm not talking only about technology)... yet there's always a chunk of our society saying how this and that is stupid to own and pointless. I realize this is a public forum for opinions, but the whining that goes on about menial things is absurd. Let people do whatever they want with their money. Cell phones as a modern convenience is frowned upon to some of you? So what if a 16 year old has one in his car for emergencies? Just because you were okay without a phone in 1975 doesn't mean people today should act the same way. How can anyone not admit the cell phone makes all our lives easier? So what if people use them to ask about how the other person's day is going? They have that convenience and they have that freedom (so long as they obey all laws). The laptop computer was created for mobile use - take your $#!t anywhere. So what if people listen to MP3s or load up a game of Solitaire? It's not its intended purpose, but it's got the capabilities - so why not use it.
EDIT>> Granted, people must use their own moral judgment about when to use the phone... but it's the same as anything else. Would you blow smoke in a non-smoker's face? Would you tailgate someone on the highway? It's not up to us to tell them it's wrong. It's up to them to realize it.
Nobody is asking every one of us to get a cell phone. If you think it's stupid, then you obviously don't need one - what more is there to the story? What more can we find to complain about ? What is working good for if you don't enjoy the things you can buy with the money you earn? Hell, if I win tonight's lottery, I'm buying a mansion for my fiance and I, even though we won't be able to use 90% of the rooms. Big f%#king deal. Relax and enjoy your life while you still have good health.
