Re: well that might be OK as an amateur
As I recall, author Piers Anthony uses all OSS for writing his novels. Maybe someone else drops it into Word later on, but he's certainly a professional writer.
And unless he's recanted several years of public statements, he wrote just about all his famous novels longhand on paper using a pencil. Certainly most of the Xanth stories, the Tyrant of Jupiter stuff and Macroscope.
At least, that's what he used to say before Windows XP.
