I find it takes me out of the experience. I get so absorbed in my books that I'll forget I even had a pen, leaving me with many half-marked books. If there's something that strikes me enough as wanting to remember, I'll write it down; otherwise, if I'm having trouble understanding the meaning in a passage, I'll reread and slow down to chew on it a little more. I hate underlining more than highlighting, because dark pen tends to scratch out words more. However, as a student buying textbooks... You can get used to anything.
