Oddly, for me the feedback of the computer is too fast for thinking. I like being able to write a bit before thinking about some details. More, I find that forcing myself to run the code in my head is a good idea. That all said, I don't do the paper thing often. Really only when thinking at a level other than the symbolic of text. Some system diagrams. Sometimes numeric. I suspect if I got good at Mathematica, I'd do more numeric thinking there.
