I live in a rural county outside of Lawrence, KS. The fastest 'net connection I can get is Verizon 3G. In a decade, I'll be lucky if WiMax has made its way out that far, but there's absolutely no reason why a telco would run a physical pipe out to me. It'd be miles of cable/fiber with me and my chickens on the other end of it.
People who live in cities and tech hubs forget the fact that there's a lot of open space in this country. Much of the population may very well might have gigabit in a decade, but there'll always be a portion of the population who just live too far out in the sticks.
