Everyone is super excited about this and I am sure its going to capture a significant market, but you have to realise what are alternatives and how much they cost.
I expect them to be utterly unaffordable at least for first half of decade.
Their biggest competitor is Iridium which offer similar service at $150 per 2kbps. I will let you extrapolate real life prices from here.
SpaceX should be able to undercut that some since they can launch their satellites at cost and using a booster that's already been up once or twice really brings that cost down.
Bigger less profitable userbase vs larger more profitable user base. The question is if the bigger userbase option is big enough to make overall profits larger than they would have been with the smaller one. I have no idea.
