Real Engineering has a video that describes the value of SpaceX Starlink satellites.
Nextbigfuture has pointed out the value of Starlink to reduce the latency for financial communication around the world.
Elon Musk has also indicated that Starlink will look to serve people outside of dense urban areas with internet connections.
SpaceX is making smaller medium pizza box-sized flat phase array links. It is unknown what the pricing will be for those phased arrays. Kymeta makes low cost phased arrays at about $30,000 each. If SpaceX and Tesla can get Starlink connections into new Tesla commercial trucks and increase the volume of production, then SpaceX could get the price down to a few thousand dollars each.
