Since it concerns me personally in our location, I found this to be an amazing statistic as far as global comparisons. And I don’t even have a smartphone.
About the time the state phone company got their public phones on just about every street corner in Brazil a few years back, mobile started growing and taking over. (It threw away millions because it couldn’t see the trend coming.) Now it’s hard to find a Brazilian without a smartphone.
And now it’s hard to have a conversation (or a worship meeting) without a smartphone turning up to interrupt.
There are downsides but advantages, too. See the link above for more.
