Scanning is a wonderful idea! I do have hand scrawled notes here there and everywhere, which I usually go through to incorporate into the story later, but sometimes I'm in such a hurry my scrawl is hard to read.

And I also dictate into my phone and it goes to print later in Google Docs, and I keyboard too. But everything that helps, helps!
I love the look of those Noodler pens but if I'm on a roll I wouldn't want to have to stop and refill. Of course just having 3 or 4 sitting there ready to go would be a solution to that, but a pretty expensive one!
