Objective-C Fundamentals book Q's

[Brian Lang]

Hey guys, thanks for doing this.

I've been at one time or another, a PHP (web application) developer, Java (desktop) developer, and now looking at the iOS platform. I do have a good background in C although I have not developed professionally with it.

What can I expect from your book to address my current skillset? I typically do better when something is taught from a "programmer's perspective".
