We’ve crossed the barrier, beyond the great divide. There’s no turning back now. Okay, that’s a little dramatic, but a new report from Pew Research today confirms what we sort of suspected anyway: That more than half of adults in the U.S. are now smartphone owners — 56 percent, to be exact. And the majority of 18-to-24-year-olds have smartphones — even if they’re broke. You might vaguely recall a similar report from about a year ago stating that more than half (53 percent) of Americans were smartphone owners. I asked Pew about this, and as I understand it, here’s how these reports differ: Last year’s Pew report found that smartphone owners represented 53 percent of cellphone owners.
