Smartphone Nation: Mapping iPhone, Android and BlackBerry Users

Over at Atlantic.com Rebecca J. Rosen has posted a fascinating interactive map that allows users to see which phones are dominating in each state, and then compare that information with other demographic data -- population density, political party registration, income levels, even obesity rates.

As Rosen writes:

The United States is a diverse place. Across the nation, there is substantial variation in demographics, political views, and health. Add technology to the list of our differences. Cell-phone makers have not had the same level of success in every state. iPhones sell really well in Oregon and Louisiana, not as well in Idaho and Florida. Phones loaded with Google's Android operating system are doing great in California, but not as well in Michigan.
