How many gadgets are de rigueur these days? I’m considering upgrading from my “dumb phone” to a smart phone, and I’m tempted to try an e-reader. At the same time, I’m troubled by the unspoken reality: we gadget people are an elite minority, a society of first-world people who have access to a network and its benefits that others don’t have. Or do we really believe that the entire world will soon be “like us,” connected into one happy progressively social network?
