Starlink is fast and awesome for sure, but is it reliable? Is it always-on? Can you count on it? Can you get a Static IP if you need it? Can you get good support when you need it? How long do you want to wait for a replacement part if you break it? What happens if a space storm wipes out some of their satellites, like recently happened? What happens if there are trees and tall buildings around you? What will happen when it comes out of beta and they actually set the cost, maybe even incorporate data caps and other restrictions. It might not be so great then.
