I haven't read these particular books but normally I have one "huge" CS book under progress at any time. It's usually a topic I want to know more about and get a basic fundamental understanding of, so mostly driven by the need for knowledge and the feeling that my knowledge is lacking in this area. That said, it usually takes me months to get through with one and often I already know some of the contents which I end up speed reading/skimming.
