Give it time. train : plane :: land line : cell phone :: terrestrial : satellite The transition won't be instant and there will still be a place for terrestrial cell service for a long time, but the future favors flexibility and ubiquity. The big challenge/opportunity will come when a non-US player arrives, like Thuraya after Iridium and the NSA can't slurp down all telephony.
