I have indeed noticed some updates coming out and have looked at the contents of the book after a couple in hopes that the examples would have been updated, but that didn't happen. I was mostly disappointed in the lack of response from Ari Lerner at the time as well.

I was also surprised by the order of the subjects. It almost immediately started of with a manual $compile function and custom binding parameters. Which I felt would be better placed later in the book, when a user is more comfortable with the angular syntax and workings.

Still, I don't want to sound overly negative. If it worked for you it must be doing something right. But sharing this experience actually triggered me to create this account after lurking for so long. :)
