Neat, although I'm more interested in when you plan on having this book out... Angular is incredibly powerful but it really could use with some more resources for those who are picking it up.
I can't quite recommend that book. A lot of the code examples contain errors and, worse, some of them are subtle errors in nomenclature (the text refers to the "myService" service but the code declares it as "service" in one place and then "myService" in another) and not jsut typos.
That's probably a fair assessment. I don't really read books like this for the code precision (heck even sample repos on github don't survive working over much time). I look more at the high-level gist of concepts, so for that it's good, and then I know what to Google next...
I wouldn't even be surprised if the book is totally out of date in a few months.
