I also take umberidge with the idea that digital books are more convenient. A physical book is more engaging, more beautiful, more real and more present than a digital book. All things that I find convenient when I want to interact with knowledge and art. Horses for courses I assume.
They’re damn bulky, though, especially when there’s an alternative that weighs nothing. Damn bulky.
The thing is, I've had a number of instances where the paper copy of a book was so poorly typeset (usually overly long lines on too-wide pages, e.g., _The Inklings and King Arthur: J. R. R. Tolkien, Charles Williams, C. S. Lewis, and Owen Barfield on the Matter of Britain_ edited by Sørina Higgins) that I actually purchased the e-book version so as to be able to read it comfortably.
Otherwise, very much in agreement!
You can't lose your place easily. Lighting isn't an issue if you buy a backlit model. Reading lying on your back or side is much easier. Traveling is easier with an e-reader. Access to wikipedia and the dictionary on the same device.
There are emotional reasons that I like paper books, but if I'm just trying to read, give me an ebook.
If the medium makes the difference between me reading a text rather than not reading that text, I tend to think that makes it functionally "better".
