This book is written as 'easy reading' and is styled much like casual conversation. It is not intended as a technical manual, but more in the nature of a conversation for understanding.
The intent of the writer is to basically put the reader at ease with the subject matter. It seems that when we get into the technical mode that people get a bit tense. Perhaps that is because of the newness of the subject matter or perhaps there is an element of dread or foreboding, sometimes with a bit of cognitive dissonance too.
But with this style of writing one can be a bit detached and simply take in the information without consequence to oneself. In today's world which moves at a frantic pace, at times it might be best to sit back and enjoy the pleasure of reading...a luxury denied us in the age of technology.
