This book is a great complement to the training guide but some chapters include some information unnecesary foir the exam like how to reboot tje computer cally runddll32 to setup API and similar ones. It has some tipos but information on monitoring optimization and conectivity is superb, and very clearly explained. I've passed my exam with 900 and have bought the Wks version...so good overall choice

This book was poorly edited. I believe that it is technically correct (unlike other books in the testprep series), but there are so many errors. I did not think that it was proof read before publishing. It slowed my preparation in passing the 70-064, and I can not recommend it on he errors alone

I would recomend using other methods of preperation. This book was ok, it did contain most of the information you need to pass. There were a lot of mistakes, the authors obviously didn't proofread this book very well. This book will become a permanent fixture on my bookshelf that will do nothing but collect dust!

I just purchased this book, it seems pretty good so far. I have found some typos but otherwise it seems real good and easy to understand. A review book like this has been well awaited. Good job.

I would really like to give the book 0 Stars or a -5. Thank goodness Dr. Chadwick was not alive and a conductor during the 1800's because based on his descriptions just in Ohio I would have be lost, caught and sold back to slavery. I know a couple of his acknowledgements and know for a fact he did not spend much time talking to them or getting their input before his final draft. There are so many sites all over the United States and Canada that I am sure Vince DeForest could have pointed out, yet he spend an amazing amount of time dwelling in Ohio. At first I was flattered until I started reading the descriptions. If he went on a tour at the Kelton House, he must have slept his way through it. There is a lot more to say about the Stone Academy in Zanesville! What about its significance in the history of the Underground Railroad? Isn't that what the book is about? The only thing about Benjamin Lundy that stuck in his mind was his "bragging about traveling more than 25,000 miles ..". A Quaker bragging, when did this interview take place? What about the Free Labor Store still standing? I could go on but I will leave a few comments for others.

I think you get the jest. In historical accuracy he gets a F, in vague research he gets a A+.

Don't read this book.

Dr. Bruce Chadwick's brief and exciting narrative of the history of the Underground Railroad is superbly written. Adventurous and refreshing from the beginning, this work can be enjoyed by both academians and laymen. Chadwick provides suspenseful tales of escape from slavery, including accounts such as the well-known escape of Henry "Box" Brown as well as lesser known treasures that I won't spoil by summarizing here.

Not meant to be an extensive historical account of Underground Railroad history or Civil War daily life, this book does provide descriptions, photos and historical details pertaining to more than 300 sites currently listed as part of the Underground Railroad, and an introduction to the Underground Railroad that is the sine qua non of the book. Chadwick also provides histories of some sites that were destroyed before they could be legitimately proven as an historical part of the Underground Railroad.

As for the previous Amazon[.com] reviewer's distaste for this work, I'm wondering what personal animosity existed between the reviewer and Dr. Chadwick. The accusations of historical inaccuracy and false acknowledgements are hardly believable. As for descriptions of certain sites the reviewer claims "vague," that would be the point of visiting the Underground Railroad sites for one's self.

Read this book, and enjoy your journey!

Since the first author of this book offers graduate courses in mobile computing, and the table of contents looked good, I bought this book at great expense. (The price is quite outrageous for developing countries). I was shocked to find that the book has very little technical details on any of the topics covered. The book's seven chapters constitute only 135 pages, which also includes about 25 photos of various mobile devices! At best, this book provides a preliminary overview of the area.

The book tries to cover too many aspects of mobile computing in an unstructured and inconsistent way. While the title sounds promising, the quality of the book is low. Most of the figures are bitmaps, even the text in many figures is bitmap and, thus, quite often unreadable. While the authors try to give up-to-date examples of mobile devices, pictures with, e.g., three identical camcorders are superfluous. However, for the price of the book the inconsistencies and errors are really annoying. Just some examples: At the time of writing the book (June 99), GSM did not have 20+ million subscibers as the authors write but almost 200 Million! Examples like WAP (Wireless Application Protocol) are based on the very first drafts, since 1998 new reference models have been published that differ much from the one shown in the book. Furthermore, many little wrong details will confuse readers: ETSI is not a successor for CCITT standards, many tables are wrong (GSM cells can cover more than 10km etc.), DECT has been renamed to Digital Enhanced Cordless Telecommunications long time ago, concepts of different systems are mixed (e.g., Mobile IP, CDPD and GPRS) in one chapter etc. It is unclear for a reader which topics are standards, which are new results from research, and what is already available for customers. A reader who knows something about mobile communications gets the impression that the authors simply collected information to some topics wherever available but did not write a consistent, up-to-date book. New information about hardware is mixed with graphs from 1994 showing average prices of cellular phones, new results from research are mixed with outdated specifications of cellular phone networks - overall a book I cannot recommend, particularly not for this price.

While this volume is dated in terms of market data and product references, the engineering concepts that it covers are highly applicable to the evolving realm of wireless communications and portable computing. This is an excelent primer in the basic concepts of a rapidly evolving industry, and many of the standards and architectures that are discussed have been implemented since the release of the book. I would highly recommend this book for individuals that want insight into the underlying infrastructure that supports mobile information appliances.
