I’ve never thought about it before, but today it strikes me as really obvious. The type of reading I do – mostly non-fiction in the business or self-improvement genres – would likely be best done on a Kindle or similar digital reader.
I like to take notes, or highlight passages I enjoy, for later review. Since I opt for library books whenever I can, this is an issue. I typically like to read undisturbed so the distraction of stopping, taking notes by hand, then finding where I left off in a paper book is problematic. Doing this on a digital device would be quicker and relatively painless.*
Sometimes after reading a paper book I leaf back through the book and attempt to outline it as a way of documenting the main ideas. This is far from foolproof though, so I’m sure I miss non-obvious tidbits. And it is time consuming.
*I wonder though, can you “take notes and highlight passages” on an electronic book you borrow from the library?
