The PDF was fine, but not great.
The biggest failing was a lack of links in the PDF. Neither the table of contents nor the index were linked so that a click could take you to the page you were interested in.
Aside from that, my issues may have been related to my PDF viewer / computer. Searches were slow, which was sad, as that's the only good way to find topical information.
