- Non-random access: we are surprisingly good at knowing where in a book something we read was, and flipping back to it. While keeping our finger in the place or places we were. You can build a working stack of locations in paper that's a pain to do in every e-reader I've tried.
- Notes/Marginalia/Markup are available on both, but with vastly more expressiveness and options on paper (though without search)
- Share/re-share/bequeath
- Some evidence of better comprehension and retention of physical reading vs screens.
- No batteries required.
- Attractive physical objects can be a pleasure to own (and a pain in the ass when moving house)
I wouldn't want to annotate or highlight a paper book - that feels like damaging it.
> No batteries required.
Not really an issue for a Kindle-like device - it lasts about 30 days without a charge, which is long enough to read more books than I'd care to carry on a no-electricity trip.
Don't do it with library books obviously, but if you own the book, try it. It vastly improved my reading experience when I started annotating.
Perhaps I'm weird in this sense but I know a couple people who remember stuff similarly. It matters more for textbooks or academic literature where I'm trying to recall specific information; with novels it's not as necessary.
I'm guessing a lot more people could remember the name of a concept that they could then easily search for in an ebook instead - seems a much more direct and practical benefit to me.
Another example is history books with image plates. In a physical book it's easy to flip to the plate section and skim through it rapidly, on a Kindle, no, and of course any color is lost.
There are other aesthetic qualities to books that are often lost, e.g. flip through a copy of Steven Johnson's Wonderland. Notice the color interstitial pages and the way images are integrated with the text. All lost on Kindle.
In general any sort of subtlety in layout/use of fonts is lost on Kindle (e.g. sidebars, or little italics at the margins summarize a given section)
There's of course the obvious issue of ease of passing on/reselling a book.
This is only a partial enumeration of the reasons I've reverted fully to print books after flirting with the Kindle.
