Even now, I much prefer writing my stories or articles in a binder book first, before transferring the words to a computer. I find that, for me, it's much easier to scribble down my thoughts, cross out incorrect words or phrases, and use arrows to add in alterations. When I later type my piece/scene into a word processing file, I edit it again.
Whilst this process may at first appear laborious, I consider it a small price to pay for portability (I can take a notebook with me much more easily than a laptop), plus a built-in extra edit.
I've writen one-and-a-bit books this way, and will continue to finish my current YA supernatural romance manuscript in my trusty binder book, one scene at a time.
So, what about you? For your writing, do you prefer using a notebook or Netbook?
