I probably didn't make myself clear.

As I said above, on most cell phone/teen threads, the parents who choose not to get teens a phone are usually the most judgmental ones on the thrtead. Often they go start other threads about being "bad" parents because they won't get their teens a cell phone, or let them have a car, or let them eat ice cream for dinner, or make them go to bed at a reasonable hour, etc. Really any type of situation where a permissive parent might be willing to do something that a less permissive parent judges them for.
It just usually evolves into a parenting debate - at least that's what I most remember about practically every cell phone thread I've ever seen on the DIS.
Cost is certainly a family factor but it's cheap to add another line to a family plan and most teens I know can scrape together ten bucks a month for a family line. It doesn't seem to me that a teen cell phone is significantly impacting anyone's ability to save for college or take a vacation.
