Query: Reads like a Sun advertisement

I must admit that I have only read the first half of Mastering EJB - I got sick of all the buzzwords and praises for EJB. It really sounds like an advertisement for EJBs and Java technology in general. If you like Sun's style of hyping their technology to death, you may actually like this book. But if you are more critical of all the promises the author (and Sun) makes about EJB, Java, components, re-usability of components in a closed-source world and hate all those articifial words that E, you will probably throw this book away...
