the electronic format is superior in every way - full text search, fully customizable/accessible reading experience. ebooks cost nothing to "print", transfer and store, and they don't degrade.
a 500 GB SD card fits 25000 rather large 20 MB pdfs/epubs. a 16 TB HDD fits 800000.
it's over. and that's a good thing.
Doesn’t require power to operate
The tactile experience is top notch, and makes for fast seeking in the book
You can sell or lend the book without permission from someone else
Edit: also books don’t have dynamic tracking or affiliate links or scams for getting you to buy something - this is more apropos to websites. Still though, I hear people say that long form is dead and internet video/short form, or even blogs is the way real knowledge is passed on.
I can give you a copy of any book I own for free
