There is a difference. The 2nd edition covers what new with the 2.0 side of Objective-C as well as having a whole section on iPhone development.From what I saw there is very little difference, if any.

I also support purchasing the book rather than downloading it - we have to support the people in our field!![]()
Of course it's worth the money (wow, what a subject title!)
Obviously, I don't set the price, the publisher does. Quite honestly, it's not that easy to make a decent income writing anymore--unless you happen to hit a bestseller. The Internet and all the free material that's available has put a lot of pressure on both the publishers and authors. Not a complaint, just a statement of the state of industry, which may also account for what you might consider a high price for the book.
