Generally I prefer to read from a book. While they are bulky, heavy, not as
fashionable as an E-Reader, I like books. I spent a lot of my childhood in the library, I like their smell, texture, the feeling of turning pages.
Also I've never understood the 'carry around' problem. But then I don't do my reading in public, or outside my home. I have a comfortable chair, or my bed.

If I have to read something related to my programming work (I.E.: Reference Material, papers, manuals), second monitor and it better be in a simple text or pdf format.
