I didn't say that there was no need to support the filetype. All scientific articles are pdf files, and I don't see that changing anytime soon. But we were talking about books.

And PDF has a convenience far beyond its use for "books;" the ability to make consistently-printable business docs is going to keep it active.
You were talking pdf as a book format when you said that it's here to stay and I showed that the sales are going down.

Based on the arguments of choosing pdf over any reflow format one would expect pdf to be the format of choice when it comes to digital books of the kind that O'Reilly has to offer. According to the graph they sold 10 times less pdf files in 2010 compared to 2008.
