It's not a generational thing, and it's not necessarily bound by income or ethnicity.
Smartphone users have become a class of their own.
The differences are miniscule, as reported in AllThingsD, but it seems there is a slight higher smartphone use for women over men, and for Latino and African American users over whites.
But according to a recent eMarketer report, the 'smartphone class' is not distinguished by age, race, gender, or income, but by behavior, which is called 'snacking' - essentially consuming bits and bites of content constantly.
In their words: "Its members define themselves by their connectedness and their sense of empowerment through unfettered access to real-time information."
The content-grazing done by this class could mean a 5-minute Twitter scan between meetings or a 15-minute YouTube break at lunch. But the people are constantly tapped in to what's going on, all via their phones.
It's not just for 'snacking' either - Mashable reports in a Lab42 infographic that half of all fitness freaks (and even just workout newbies) are using their phones while excersizing, "whether for checking email (33%) or tracking their pace (43%). Listening to music is the most popular way to incorporate mobile devices into a workout (91%)."
By the way, a reported 48.5% of those smartphone users in the United States are tapping on Androids.
Do you consider yourself a part of the smartphone class?
