Fifty-six percent of American adults now own a smartphone, according to Pew Research. But what do they use them for?  Research from Kansas State University finds that people want smartphones solely for entertainment.

Marketing Professor Esther Swilley says the majority of participants in her study said they're attached to their phone because it serves as entertainment, not because it's a way to communicate anytime, anywhere.

A surprising find in this study is that smartphone users say their phone doesn't allow them to express themselves. Overall, people would rather use their phone to have fun than be productive, and they're willing to spend money to do it.

"People do not want to lose their cell phones, but they will buy the latest and greatest in a heartbeat," said Swilley. "They want their cell phone. They don't want to lose their phone, but they don't want to be responsible either."
