So my husband bought one last week while he was out shopping.  I found this nearly /facepalm worthy.  We've been playing since original beta.  Why would we need the strat guide?  Besides, it'll only be out of date in a couple weeks anyway.  That's how those things go.  So the husband actually says that he just bought it for bathroom reading material.  And true enough, it has sat in our bathroom ever since, along with at least six months worth of Game Informers, and the Ultimate Bathroom Book. 
 
So one day this weekend, I happen to be in the bathroom long enough to need some reading material.  I pick up the strat guide and start looking through it.  Sure enough, this thing is a wealth of information, and it's much better than I expected.  The guide is obviously aimed at new players - telling them how to pick servers, how to choose what kind of character they may want to create, etc.  But there are some other interesting things too, like a level-by-zone guide, class and spec guides, etc.  Even includes what abilities/spells each class gets, and when, and what they all do.
 
From what I've read in reviews, this guide doesn't give much info in the way of new instances.  But it's great for people who have never played the game before, or who have never played a particular class before.   I definitely found it worth checking out just for the stupid little things I never knew.  (Like I didn't know that when you're swimming, you can press X to dive down... I always just used my mouselook and WASD.)
