Not all cells

are used as additional phones. I know of several people who use their cell as their only phone. They have no landlines at all!
My sister is in college now and if she had no cell phone, she could not call us at all because the dorms are no longer equipped with phones.
So no, it is not necessarily a "luxury" item.
