"Consumers have other options (mainly iOS)" Two or three competitors in a space does not a robust market make. For one thing, it is very easy to create side-channels of collusion between the competitors. Just as one example closer to everyday life, think about how easy it is for two people to share information in bridge or spades (the card games) without overt communication. I guarantee that side-channel collusion is happening between executives any time the number of players has gotten small enough. How many times have regulatory agencies used the existence of only two networking/telecom providers in an area as a basis for deciding that a market has sufficient competition to allow another merger to go through? We can see the adverse effects of the lack of competition in the terrible customer service and product quality in that industry. Why can't we see it in our own?
