Query: Not Good.

I bought this book when starting my first full-time Solaris admin job. I read the bad reviews, but bought it on the basis of the Sun logo. MISTAKE. Any useful information in the book is easy to find (and usually easier to read) online or in man pages, and useless information abounds. The whole thing is in a disjointed, un-fun style. It's dusty now, but I use it as a coaster anyway.
