Why would I want to download Microsoft eBooks?
Got a link to something useful? Oracle eBooks? Apple eBooks? Linux eBooks?
That is a refreshing attitude. Most of what Microsoft publishes is "How to Make Our Crap Work". Since they now style all of their documents after web pages full of circular links, there is almost no content. They used to print quality documentation twenty years ago. People nowadays mistake contentless pages with plenty of links to other empty pages for documentation.
Very ping-worthy for your Microsoft ping list, I think!
