You make a valid point, but I was referring more specifically to web based services and more tightly controlled micro-commerce platforms and operating systems.

You make a valid point, but I was referring more specifically to web based services and more tightly controlled micro-commerce platforms and operating systems. Considering the high market share of Android I can't fathom ever not building both an Android and iOS version of an app, regardless of cost you have one or the other to fallback on. If both fail however, then you have a mega problem.
