I wish I could say that I hate to say “I told you so,” but I don’t. When Verizon began carrying the iPhone last year, it made the mistake of offering an unlimited data plan. This was a dumb move, I argued then, because it was clear Verizon would later have to scrap this approach. Unlimited plans reward data hogs at the expense of everyone else: If you’re streaming puppy videos all day and I’m just surfing the Web, why should we pay the same rate—especially if your puppy videos are clogging the network and ruining my Web searching? It’s fairer—and, for most people, cheaper—if, like in everything else in life, we pay for only what we use.
