Interesting question. I guess I hadn't really thought of it this way, but I've separated capturing and editing of thoughts when I use my BlackBerry 'Voice Notes Recorder' app as one of my Collectors to capture ideas when it is not convenient or safe to write them down. For example, I've had some wonderful brainstorming / thought-capturing sessions this way while driving. Dictation software would be another way to do this, as I believe you mentioned.
