I’m actually a little puzzled by the Apple policy; the technical side I mean, not the business issues, which Gruber explains with ruthless clarity. I can see Apple wanting to enforce the use of their APIs, but the compulsory linkage to the Objective C programming language makes me feel like I’m missing something; where is it carved in stone that it provides the optimal, impossible-to-improve, way to use the iPhone APIs? And if nobody’s allowed to try anything else, how will we find out?
