The important comparison here is with the traditional 250ms+ pings from previous satellite internet services. Starlink at first will be aimed at hard to reach areas, for people that pay a lot of money for 250ms+ pings, 10Mbps/5Mbps services. 20ms is a good start and a clue that good online gaming and even cloud gaming will be possible with a satellite internet service.
My parents in the boonies get ~3 mbps with centurlylink DSL, and I believe it is erratic at that. While netflix streaming is possible, my young brother in law staying with them currently is tearing his hair out because fortnight and COD are unplayable on the connection.
Even 10 mbps would be a godsend for them, forget something like 60 mbps, that would just be utter gravy.
From reading the starlink reddit, many people are even much worse off than my parents.
All that said I do worry that sure, 10-60 sounds OK/good now, but it's a sliding scale and BW demands are always increasing (hell my first cable connection all those years ago was 1.5 mbps I believe, now it's 400). I guess/hope they will keep launching satellites with more throughput and better hardware over time.
This is still a way from reality but seems becoming closer to reality, cautiously optimistic again. The ground stations are still an issue we haven't heard much about.
Decent internet literally able to reach anywhere (even say, remote national forest where there's zero cell signal) could be a bit of a gamechanger for the entire world IMO if it came to fruition.
I do think the price is likely to be higher than we expect. The value is there, again for people like my parents, and many others, it's probably easily worth $100 per month. There are people who spend tens of thousands on paying for cable to be extended a few hundred meters to their homes and things like that.
