Ok, I'll be fair. I've only made it 5 pages in to the book so far. Basically the TOC and the Preface. The last page of the TOC fell out already... It's a brand new book, just arrived today. I know sometimes the binding doesn't take well.
The other thing I saw that bothers me, after just thumbing through it at random, is the Typesetting. There are large sections of pages where they didn't put anything. You think you're at the end of the chapter, only to turn the page and get a paragraph that was too large for the previous page. Instead of carrying over, they mid paragraph, they move the whole paragraph to the next page. Which of course used up more space. Otherwise the book would probably only be 100 pages. (Well maybe not).
Lots of screen shots, and they drag text from the paragraph with them too.
Minor annoyance, they mention customer support in the preface, but then leave out all ways of contacting said group. Unless of course they mean the Errata and question sections on the next page, after the large gap at the bottom of the Customer Support page. Probably about 1/5 of the page. (The section between the boarders). They are also trying to get more writers in the preface too.
An O'Reilly book, it's not. I'll do a more proper update later, after reading more of it.
