I've been a proponent of e-reading for many years, but have not really tried to flip books very often. An advantage of E-reading is that many books are stored at once, all keeping track of your place in the book.
When the kids were younger, I used to read to them (e.g. "Lion, Witch and Wardrobe") and as they were falling to sleep, switch to whatever book I was reading at the time.
On and off, I've jumped between a couple of books, primarily as some I wanted to read, but wasn't immediately captured by it.
I "accidentally" started reading "Hulk" by Peter David, which is the source material for the 1st Hulk movie (with Eric Bana). The movie wasn't very good, so I had little hope for the book, but being a comic nerd, I started anyway. The book actually is pretty good, and provides the necessary details that didn't come across in the movie. The "book" story differs from the "comic book" origin for Hulk, but is an OK update (search for healing using biotech and gamma radiation), which goes awry.
The "other" aspect of the movie is an abusive relationship between very young Bruce and his father, who was a military researcher who eventually murdered Bruce's mother. The book does a better job than the movie (Nick Nolte played Bruce's dad) of covering this topic.
Alternating with the Hulk is "Candle in the Dark" by Richard Dawkins. I didn't manage to get through Dawkins' biography, though I may continue at some point, but have liked the first few chapters of his book. This book returns to discussing science, with biographical tidbits of where he was and the circumstances of learning (e.g. in Panama on an island in the canal zone), which, for me anyway, is a much nicer way to connect biography with the subject of interest.
The third book in the mix is "Cosmos" by Carl Sagan, which I'm sure I read in the past, but ran across it again and thought I'd give it another read.
Basically, I read a chapter or two of one book, topped off by a chapter of another. I'm seeing if I can keep the story fragments in check as I read something else, and use each book as a reward for another. I love to read, but have trouble finding time to stick it in the schedule - hopefully this mutual reinforcement circle will keep me going for a while (and Christmas break is a'comin).
A second reason for playing around is that I have a Samsung tablet, which I really bought to support smart watches, but find the 7" screen and Moon Reader software work for this to be an acceptable e-reader (note, actual e-paper e-readers still rule supreme for reading text - books like Cosmos,which are illustrated are likely better on an LCD screen). A further add-in is the software "LifeLog" from Sony, which tracks lots of information silently - if I carry my tablet around it will track steps, distance, driving time, reading time, music played, movies/media watched, social media searched, and put it into a timeline. It even logs pictures taken, so you will have an independent date-stamp (and the other context) with your pictures. The "value" of this may be arguable, but I kind of like the idea that I can scroll back to last year (assuming I keep the software and it logs for the duration) and see what I was reading, watching etc. Assuming I keep this active, it might be nice to answer questions like - "what was that song we were listening to in the car" or "what the heck was I doing last weekend).
I've only been using the software for a few days, but was surprised that it tracked my commutes - I can now "know" when I got to work, when I had lunch, when I went home, when I ferried around the kids for events - I was surprised that I spent nearly an hour in the car just on short duration trips - puts gas mileage into an appropriate context as well.
