> As an avid reader (and sometimes writer) of technical books, it's sad to see the, perhaps inevitable, decline of the space.

When I think about this, I get a little bit scared. Imagine books going away, even if it's just the subcategory of technical books.

The printed word has been around for a long time. The number of things that have been printed has always gone up. It really bothers me that that's changing.

PDFs and websites are no substitute for printed paper bound in a cover. PDFs and websites are a fallback when the preferred media isn't available, they are not supposed to be the preferred media. All of the of the reasons that people have given over the years are applicable when it comes to why paper is superior for this.
