As the co-author of this book I'd like to say the following:

* Yes there are some typographical errors
* The example that illustrates the correct slash, the premise was that the reader would know we meant backslash since the example showed one
* The illustrations are one of the best parts of the book. They are attractive, easy-to-understand, well-rendered, and, lastly, relevant. We did not willy-nilly throw them in, we gave a lot of thought, time, energy and discussion into deciding what should be an illustration and what shouldn't. Keep in mind, as you stated yourself, this is a book for someone who doesn't know these concepts
* We must have missed the memo that said it was necessary to be stand-up comedians to write tech books. Puns are considered bad English. The book had a chatty feel to it, but clever little puns isn't our style.

We're sorry you don't like our style. Your complaints about typo's are dead-on and are being addressed in errata.
