Everybody has their own way, and I suspect you won't get many helpful replies.
For lengthy reading sessions, my preferred is to make myself a cup of coffee and take my tablet outside to read. I have a nice pergola to sit under, cushioned chairs, cheerful birds and soothing breezes. Most of my family are night owls, so this is an early Saturday morning activity for me, and only for part of the year, since I find it less comfortable when it is cold and/or snowy outside. (In the winter, I still make the cup of coffee, but I sit inside at the dining room table.) These books are ones that I have been wanting to read, usually for some time, and I want to take the time to really take them in and get as much out of them as I can.
All other times, I just read whatever I have handy on whatever device I happen to have with me. Usually it's something not too deep or thoughtful, that I can drop at a second's notice because whatever small bit of time I have has been used up. (Such as the end of one of my children's music lessons or the child I'm picking up *finally* leaving his friends and finding his way to my car.) These books are less detailed and I don't get so involved in them that I can't handle an interruption. I think of them like daytime TV -- even if I forget what has happened in them, in a few pages, I'll be able to pick up the plot again.
