> It's a book that is a PDF at some point before it hits printing presses. What is there to make at all? The kindle has been out for how many years? how is the book so different when reading it on an e-ink display? Just anecdotal information : my Kindle regularly reports the infamous "Low memory" error and closes down the book when I try to read my 8 MB copy of "Programming in Scala, 2nd Edition". It definitely detracts from the reading experience, especially knowing upfront that you can read only a few pages before you hit the dreaded error. I suppose Knuth's book would be equally, or more, "heavy" and the Kindle would choke on the pdf versions.
