We got our first one not quite 8 years ago, not enthusiastically, because we were not amused by some of the antisocial behaviour practiced by people using cell phones -- inappropriate use in the car, conducting a meeting in a restaurant while their lunch mate sat being ignored, phones going off in concerts. Well, much of that has now been fairly universally acknowledged as inappropriate so it's not as much of a problem any more, but in the earlier days...
My Dad, then 84, was living with us, and was quite ok being left on his own for the most part -- when we were both at work, etc. However, occasionally he'd have a crummy day. That was OK while we were at work, because he could reach us, but then it happened one Thursday when we had a critical rehearsal in the evening. Intellectually, I was certain he was going to be all right, but I could not leave him because he had no way of contacting me if I had called that wrong. Rob went to the rehearsal, I stayed home, I was absolutely right about Dad, and he felt like absolute s**t being "responsible" for my missing rehearsal. Rob looked at cell phones the next day. The number of times Dad actually used the number in a situation like that, I could count on the fingers of one hand and have some left over, but the freedom it gave us was phenomenal.
And then we discovered all the OTHER ways it could be useful. Before long we had to figure out who needed it more if we weren't together, so when our carrier offered an upgrade on our contract adding a second phone at a nominal cost, it was a no-brainer. We're still using those same phones (Motorola), though when we can no longer recharge our batteries, we'll have to replace the phones, cuz they don't make 'em no mo' -- we may have to replace mine sooner, 'cuz it's starting to act like it's possessed -- doing weird things without having received any instruction to -- like turn itself on
Never mind, the beast has served me well, and I can't imagine not having that convenience now.
On the subject of people using cell phones in cars...no we don't want to go there in this post.
