The pricing will be higher than 4G. The data caps will stay similar. Carriers are not charities and don't operate at cost - if they can charge us for extra value, they will.
Why don't I have a home-based line? Are routers illegal now or something? Are the receivers locked down and proprietary? Is someone taking my computer away?
I'm skeptical, very, but the appeal is obvious if it works and the pricing isn't obscene.
