Sure, there are always compromises. I wasn't claiming otherwise. I was merely pointing out that ramping up on a particular platform is nowhere near as easy as the parent suggests.
Games are a bit of a special breed, though, and there are several game engines out there that hide the platform pretty well. I draw a bit of a distinction between "building and iOS app" and "building an OpenGL app that runs on iOS". The latter is much easier if you lack iOS experience but have the required OpenGL skills.
