Computer screens aren't much better: I have a hard time reading multiple pages in one sitting, and reading a book one page at a time is rather ineffective. I found out that there were several free audiobook playback apps in the Google Play store and that many of the greatest science fiction classics were available in audiobook form. The audiobook app I use (Smart Audiobook Player) is nice enough to automatically stop playback if the earbuds get unplugged, and to go back some number of seconds when playback is resumed.
