Me (for a client). I got it in January 2021 and deployed a few weeks later. At 10 below zero F in a fairly stiff wind natch, quite memorable :). Deployed up near 45°. This was of course a generation 1 circular unit, which actually turned out to be superior IMO since it has zero need for their router though it does have a fixed cable. I used an SFPethernet adapter to bring the signal the rest of the way to our OPNsense router and bypass any grounding issues in that respect, it's functioned continuously ever since. First few months as warned there were occasional dropouts, but I could watch those steadily become rarer and rarer as the weeks went by, and the bandwidth go up as well as more sats came online. There was nothing significant long before it went officially public.
Less anecdotally, Starlink passed 400,000 customers as of a month and a half or so ago [0]. I wouldn't be surprised if it was pushing towards the half million mark now or fairly soon. They're limited now in terms of terrestrial cell density primarily, and that cannot be solved without more and more powerful sats which can actually shrink the physical cell size and improve beam count and bandwidth. Mobile/RV is therefore useful for them because it's lower priority with no guarantees, but that's ok for that usage model. The times where it will tend to be very important are in remote areas where cells are not full, and the times where cells are full there is also more likelihood of LTE, and RV can by definition move around if necessary. Maritime (or aircraft for that matter) obviously also fits those current limits, the oceans are near empty of Starlink right now and it's high revenue per user given the competition.
