I don't think it would be all that difficult to learn the language of objective-c, but there is always more to learn the just a language. JS, HTML, CSS, require a brower, and a text-editor. I don't see many people building iPhone apps outside of xcode. And that stack seems to work well, but when a person who spends a lot of time with the browser model of development, try the xcode way of development, there can be a shock sometimes. Its a metaphore change, that can sometimes be hard to wrap your mind around. I also think it goes both ways. I would also argue that your premise that HTML, CSS, and JS were not designed for web applications, is invalid, because we can't just look at technologies for what they were suppose to be used for. Plenty of stuff has been developed for one thing, but ended up doing another.
