“For example, Sun Tzu’s The Art of War is best read by opening a page at random and reading it.”
Easily done with an electronic book.
Not really.
If you leaf through a book, you can stop wherever an interesting word or phrase catches your eye. With an electronic book, you either have to rapidly slide the pages across with your finger, which I suppose is good finger exercise, but you can’t really go through the pages very fast if you want to see any words, and it takes a tediously long time to move any significant number of pages. Or you can make the pages small, in which case, you can move several of them at a time, but you can’t see any of the words. Being able to see the words and rapidly thumb through is essential for my reading style. And using the word search function does not help. Also, I remember parts of books by where they are in relation to the covers, whether they are on the left or right page, the shape of the paragraph and words, etc., qualities which are lacking or severely limited in electronic format.
