Overall, the presented example demonstrates that anyone -- including and perhaps especially salesmen -- can write a god-awful sales pitch if they don't understand their audience. The Unix book states its value in the title (if you don't have a general notion of what processes are or why they are important, you're probably not in the target market), and establishes an ethos of trust (by making specific and concrete statements about its contents) while addressing the most common logical hang-up of would-be buyers ("is this yet another book a crappy introduction to the topic? Will it teach me anything I don't know?") The Unix book, contrary to the author's opinion, is an excellent sales pitch. But it's aimed at a technical audience, not the average consumer or a salesman.
