Customers actually willing to pay for a service in an environment that provides no alternatives.

Coming back to the initial question: we may or may not find the optimal application for the m-dev sector, but these examples above illustrate that even a capitalistic approach will be accepted by the market. Hence the idea to start this as a business in the first place.
