What I'm getting out of this book (currently reading, thanks to a JavaRanch book giveaway) is a view of the pro's and con's of EJBs, and when to use alternatives. EJB for quite a while was bandied about as the end-all, be-all technology that everyone had to know to consider themselves a "real"
Java developer. 'Bitter EJB' does a good job of showing what EJB is good for, what it isn't so good for, and what some reasonable alternatives are. Given the breadth of Java technologies and acronymns out there, having someone with real experience in the technologies show the lay of the land is very valuable, if in nothing else, in helping me determine where to focus my time.
