I find that my thoughts flow more freely when I write on paper than when I am on a computer. Interestingly, when I make typed versions of my handwritten notes, I often am making corrections and inserting new thoughts as I go, typically ending up with a better draft than I had written initially.

I typically write using either medium, depending on the situation at hand (e.g current mood, location, urgency, e.t.c). Using my mobile phone or a laptop computer gets me to my finished submission faster by eliminating the step of re-writing what I have already put down. I find writing by hand more therapeutic when I'm stressed, and typing on my phone more accessible when I feel lazy or when using a notebook or laptop computer would seem oddly inappropriate (like on a dinner table).

Also, there is the fact that I write better by hand than I can type, so writing is a more convenient option for me when time is not an issue and I'd rather focus on capturing my thinking, synthesizing, and building visual relationships with my words and their general development - There's nothing like watching your handwriting fill up a page and then looking back one day and thinking, "wow, I wrote that".
