Now I'm going to have that song stuck in my head. :P

The thing about writing in this day and age is that you can go back and change things MUCH more easily than you could in the day of typewriters. And even if you do just use a notepad and pen, thats fine too, that can be scribbled out and corrected as needed too. I was amazed to find out that Neal Stephenson, Mr. Technocrat himself, writes his books in notebooks first.
