Two years ago I would have been an integral part of the computer-enabled-me-to-write camp. But now, I'm not. This summer I started going back to school in an attempt to broaden my education - never a bad move, or so it's generally agreed upon.
During the first weeks of attending classes I was utterly confused how to cope with it. I couldn't use my MacBook in class because constantly typing on it is simply too noisy for myself (while also listening to the lecturer). Instead of reverting to pen & paper, like most students did, I started using my ipad with a special pen for writing on the screen. That did the trick for me, but it showed something I never expected before: whenever kissed by creativity's fleeting spirits I tend to write in short and intense spurts. Usually, I would grab for the laptop and start jotting down whatever insight chased through to my mind. Unfortunately, this would soon transform into an editing session as well, and as soon as I would go back a paragraph to rephrase something, it would be the beginning of the closing stages of that particular session.
My ipad experience encouraged me to try for a different approach: grabbing a pen and a paper-notebook for those times, letting those moments of sheer brilliancy(ahem) last a lot longer since I'm never tempted to start edit my utterances.
Very personal, works for me kind of putting it: the handwritten manuscript (and yes, I do include my handwriting on the ipad here) is all but impervious to editing attempts, while the computer is the perfect tool for exactly that. Obviously, it is doable either way, tools are just that: tools.
A nice side-benefit: as soon as I discovered which tool works best for me, my writing became a bit more ... satisfactory; not necessarily better, but not so much of a chore as it has been occasionally. The "hard working" part of writing got easier, if that makes any sense at all
