According to a recently released study, there are more than 5 billion cell phones in use around the world today, with 20% of those just coming into use in the last 18 months. More and more, people are either ditching their traditional land lines or relegating it to a secondary role, especially in large metropolitan areas.

A few months ago, when we polled readers on whether or not they still needed their physical White Pages phone book anymore, an overwhelming number of respondents voted “no.”

So, in the interest of pseudo-science, we now want to know just how frequently you use your land line compared to your mobile — or if you even have a land line at all anymore.
