content: I bought the first edition of this book - which was about 700 pages;It cost me $44.95 - and the book was not worth a penny! I believe the 2nd edition is better - because it has some extra pages and these last few pages are supposed to be better! I find that hard to believe ... The authors do not know how to write a technical book - they are belligerent! The book wanders all over the place - no details at all - or none of any consequence! If the publishers had any conscience they would send me the last section of the new edition FOR FREE! This was one of the worst computer books that I have ever run across ... AVOID other books by these authors!
