For me, the experience of reading drastically improves my take aways from the actual reading. I love my kindle, but actual paper books win every time (As long as I'm near my bookshelf). A lot of my time reading, is spent re-reading and eBooks haven't gotten that interface down yet. Sometimes I catch myself having zoned out 2, 3, 4 pages ago and being able to flip back and skim through to pick back up at the last part that I was fully cognizant of.

Sometimes I reach a point in the story that suddenly makes something that I read in chapter 3 or 4 much more important, it's way easier to leave one finger where I am and flip back to that pivotal moment (especially helpful if I had put the book down for a few weeks before picking it back up again).

Sometimes I'm having a conversation with my fiance later in the day or the week and something that I had read was really relevant to the conversation even if I didn't think that it was important enough at the time to highlight it. If I had read it in a physical book, I have an idea where it was physically and can usually find it in a couple of seconds by flipping through the pages. If I had read it on my kindle, then I just have to do a mediocre job of paraphrasing a beautiful turn of phrase.
