There is a huge difference in latency between existing satellite internet services and what spacex is looking to launch.

It sounda similar to fiber latency. Ive never thought about this before but the amount of time for a round trip to a leo satellite, shouldnt that be in the range of 10 m/s. (1200 km / 300,000 km/ s) = 4 m/s x 2 i wonder whats the complete breakdown, is most of it inter satellite optical communication? Does this offset the additional 8 ms because its a simplified topology?

Yes, SpaceX etc will be low Earth orbit, and the satellites will be a mesh network.
