I just  happened to start playing with Unity the last couple of weeks and noticed the Unity 3.x Game Development Essentials was written by Will Goldstone.
His video tutorials have been very good and helpful so I'm expecting the book would be just as good.
Also the book seems to make more use of C# instead of Javascript on the coding side which is another difference.
The Unity iOS Essentials  book would also be great to have especially since I have been writing native iPhone games and I'm sure this would make it a lot easier.
Does the iOS book require the Pro version of Unity though?
