2) Apple’s ecosystem is designed to create lock in and generate monopolistic profits. This actually is the goal of all businesses until their market becomes mature.
3) At the mature stage, businesses seek to compete on price and everyone’s “economic profits” are lowered to zero.
I don’t know if storage is at the point where it can be offered at breakeven at $20/year, but if it is, congratulations, you at least helped ruin Dropbox’s “greedy monopoly”. That being said, you have little chance at ruining Apple’s monopoly. You can decide to hurt it though by offering your product on Andriod for $20/year, and Apple for $28/year.
You also gain the benefit of targeting the “right customers” in the sense that Andriod customers are more focused on price, where Apple’s customers are more focused on looking cool. (no offence meant for either group, just simplifying for the sake of it).
I’d love to hear how you are able to gain such a huge cost advantage over the other companies in this space.
