Query: Solaris 10 Disappointment

This book is NOT a true reference book for Solaris 10. Rather, it introduces Solaris 7-9 to a novice Unix user with only a few references to Solaris 10 features. And even on those few Solaris 10 items, there are not enough examples or configuration ideas. Based on the paucity of relevant information, one could not even use this book to determine if an upgrade to Solaris 10 is warranted.The purchase of this book was a complete waste of money.
