If you've had any experience developing in multiple languages, aside from objective C, you'll probably get the same reaction that this guy did:
I bought the book and read it, watched the movies, installed the IDE and I still can't bluff my way into an app that simply states, “Hello World!”.
Thank goodness that there are some incredibly intelligent developers out there who recognize this and have come up with a great solution. Since most developers are developing for the web nowadays, one talented group came up with a fantastic solution, PhoneGap.
Thanks to Stephen Coley for the tip!
