Query: I don't believe it

I can not believe that the publishers are still promoting this book. Not only does it NOT cover some of the amazing features of Solaris 10, much of the content relates to earlier releases of Solaris and a number of the features covered no longer exist in Solaris 10.I felt I had completely wasted the money spent on this book. I was appalled at the content and lack of attention to just what Solaris 10 is. Very disppointed.
