It's official: Smartphones are no longer a niche product. For the first time since the Pew Research Center starting tracking smartphone ownership, more than half of American adults now own one. Fully 91 percent of adults own a cellphone of some kind, and 55 percent of those say their phone is a smartphone. The more affluent and younger you are, the more likely you are to have a smartphone, but most young people consider smartphones a must-have; they're more likely to have one, regardless of income.
