I have a tech review pass over the chapter on the [REDACTED] chapter and an errata pass as well. That should all be simple stuff. The book also had a title change, now its Core Animation for OSX and iPhone. I'm really excited to be done, and very much looking forward to seeing it @ my local Borders :).
Also the iPhone book is in 'pub review' which means it will be hitting beta RSN, can't wait.
