Hillegas has some words on his website about the differences between 
his second edition (Tiger) version and the brave new world of Leopard 
and Objective-C 2.0, so a book plus a web "errata" is pretty close.

The main thing you'll have to watch for: Objective-C 2.0 has garbage 
collection available, like Java and scripting languages you're 
familiar with, but it's off by default, and earlier Macs don't have 
it. You'll probably have to learn the old way, "retain and release," 
which is unique to Objective-C.
