Computers are distracting, and working with them as a rather easily distracted person is often not so productive. Even more so with Internet. Thus as an aspiring author and philologist I use it as a device for gathering, storing and manipulating information, and use pen and paper for creative activities. The limits are all physical and tools simplest, so all I have to, and can do is to transfer my thoughts on paper. Then I type them with a typewriter for having a product that lends itself better to editing and being read later, as my personal handwriting is, a bit too personal. Having it written on a typewriter again helps me avoid distraction. Then I edit my draft and retype if need be. I find that screen editing is mire prone to hide or produce malformed paragraphs, typoes, incontinuities and the like, as I tend to read what surrounds my edits. But the review&rewrite approach requires me to review each time I want to commit my edits writing anew the manuscript. I am more productive this way.
Furthermore, it's way more fulfilling to have created a physical form of my thoughts, that can exist as an object. It's more pleasing to handle paper, reread my work and edit it freeform with a pen. I feel more engaged, and I have a better memory of what I write on paper that what I write on computer.
I don't know if this situation has any backing research but I guess making such research would be yet another unnecessary distraction for me as a creative.
For what it's worth, when referring to a thing as outdated, one needs to ask himself, "is it, really?" Is a digital successor of an analogue or mechanical gadget able to produce a strict superset of the effects of the latter? I think, in photography, music, plastic arts and literature the answer is no. And unless the answer is yes, the gadget is not outdated. Even if ninety nine hundredths of the effects are reproduced, and many new are added, for that one hundredth of the effect, the older tool is still valid, more so if that's what the author is wanting.
Besides, today's things have less glory and object presence attached to them than their older counterparts. It's normal to want that and seek that I think.
