Should There Be An Age Requirement For Cell Phone Ownership?

If you're a parent, you've probably spent too many hours talking with your fellow parents about how to 'parent' the use of a cell phone.  (Yes- 'parent' is a noun AND a verb in the 21st century!)  Here is an interesting twist on the discussion.  A parents group in Colorado wants to legislate a ban on cell phone ownership for those under the age of 13.  The group Parents Against Underage Smartphones, or PAUS, is the nonprofit group pushing the proposal.  Under the proposal, retailers would report the age of those to whom they sold the smartphone.  I guess it's good that the parents and kids wouldn't get slapped with a fine.  However, isn't this a discussion for parents and their children to have?

As you might imagine, the retailers and many parents are not happy about the proposal.  What do you say?  How old does YOUR family say you should be to carry a cell phone?  Is this something the government should step into?
