My dad's house in Maine is at the very end of a DSL connection. He get up to about 1Mbps down with a tailwind--which is barely usable even for non-video. I couldn't really work from the house. (And there's essentially no cell service at all.) And the neighbors further down the road basically have nothing at all other than conventional satellite.)
That was superior to the 4G service they got. Just because it is 4G doesn’t mean it is services well and not overloaded even in rural areas.
Starlink will be the first real viable high speed connection they will have ever been able to get
