Query: Disappointed with this book

I purchased this book from our local bookstore. I browsed through the pages and liked what I seen. I then brought this book home and excitingly began reading and attempting to follow the "Try It Out" exercises. In reality, I spent too much time struggling with the typos, inconsistencies and missing steps.After about two weeks, I gave up using this book. I just recently discovered Amazon and more importantly, discovered the customer review section. I'll pay special attention to this section and choose my next book when both a "Look inside this book" feature is provided, and after I decipher which reviews are real versus those from those sponsoring the book (two highly rated reviews from the same location on the same day).
