I am very curious about this project and hoping it will improve my slow wifi. Is there any information on when and where it will be available?
No, not yet. Elon has stated that they want service by mid next year (2020), and given that they only need six launches (this is the official first launch, the other 60 satellites were testing various things), they might make that date. I'd give it until end of 2020 though.
I think I remember that they said initial service area would be southern US, so we would be covered (I see you're in Encinitas, CA).
No word on pricing. My personal guess is $120/month with some sort of overall monthly datacap and/or extended pricing for more usage.
BTW, this hasn't been announced yet, and still needs to go through city council approval, but there is a company gearing up to bring gigabit fiber to all of Encinitas. Initial service to be end of 2020, early 2021. It will almost certainly be cheaper than Starlink with no data caps.
