I mostly stopped reading paper books, as I do almost all book reading through Libby app on my tablet that has a high resolution display like most tablets produced in the past few years. It's a superior experience than a paper book in almost every way.

At work and home, with 4k monitor, it's so much easier to put multiple reading materials side by side and read / research across.

In 2012, even on the state of the art computer systems, the reading experience wasn't as good as it is now.
