One of the points I was trying to get through, and perhaps didn't do a great job of, was that I keep seeing people/apps trying to use HTML and various wrapping frameworks / toolkits to create the look and feel of an iOS app. Even worse, many of these "apps" don't even need to be apps (end of the article).

We went this route too and hoped we could re-use lots of code we already had but, as you say, the right tool for an iOS app is Objective-C. Un-JITed JS inside a wrapped app with a zillion Objective-C stubs using the DOM in a view-like manner its not meant to represent just doesn't do it.
