2008-02-08 Good enough for the 70-236 cert,

First the negatives
+ Loads of mainly minor editing mistakes everywhere, the main body of the text and Q+A at the end of every chapter,
+ The additional tests on the CD are pretty good, but annoyingly the Q+A are not alligned with the book. In most cases you have to go through 2 chapters before being able to test yourself.
+ In the last chapter LCR is not taken through its logical conclusion.
+ The online site does not provide an errata/corrections list.

Postives
+ Covers the material well enough
+ Each chapter has at its end a Q+A section, to re-enforce learning.
+ You get Exchange 2007 32bit+64bit on to DVD plus additional questions on a CD.
+ loads of screenshots, text pretty easy to read

I used this as my main study tool and passed with 96%, so it does what it says.

I would give it 5 stars, if it didnt has so many annoying errors. I think it is unfair and too harsh to lose more than a single star, as

1. This is a technical book and it has a limited life span (3 years max).
2. The authors and publisher are in a race to produce the book for people like me, I rather have the book now with a few errors rather than wait for another 3 months.
3. Most of the errors probably will be corrected with time.
