Do you have the paperback or the hardcover? – Marco.org. I agree only insofar as the interface is rendered well enough for it to disappear and let you focus on the content. I cannot read ebooks comfortably on my Kindle Fire or Kindle for Mac, whereas reading on an e-Ink Kindle or Kindle on iOS I can ignore the medium and just read. Similarly, I have paper books I just couldn’t get into because the typesetting was so poor that it kept distracting me from the content.
And are of course there are some (rare) exceptions to Marco’s conclusion. For example, I don’t think reading House of Leaves on any current e-reader would be remotely the same as reading it on paper.
