Amazon's FMA is so massive here. And given their insane customer-obsessive focus that manifests itself in price, convenience, selection, innovation, etc...well, all I can say is "good luck" to the challenger(s). The company basically reads The Innovator's Dilemma on an ongoing basis and keeps strategizing on avoiding a traditional fate. I would not be surprised to see them create a useful version of ST:TNG's replicator within the next 50 years.
