An earlier comment reported, "it doesn't address theory of GIS programs in general that well, and I felt like my hand was being held a little too much in some things." I certainly agree. The book is simply a series of examples. The examples are repetitive in part. There is very little explanation. Using up 10 pages to demonstrate drag-and-drop functions is really not necessary.
