I've got to go with the "none" crowd.

I don't consider coding an easy or natural activity to me... until I really get into sort of a zone. Sometimes I have to close my eyes (as well as ears) and stop staring at the screen... so that complete lack of input lets my brain percolate a fresh way of looking at a project.

What can I say? There's lots of different mind-styles out there. Took me a long time to find my own.
