I read almost exclusively on my ereader, so “two books in different places” does not apply to me. But years ago before the ereader existed I also self-disciplined to one book at a time. If I don’t, my reading will become like my internet browsing: chasing my interest of the moment, half reading something about it, going on another chase and never properly engaging with one subject. Of course some people will be better at context switching and the discipline to actually finish the multiple books they’re reading…but not me.
