Well I've written about 5000 words of new fiction this weekend, using the Dragon voice recognition software. It seems to be very useful. I finished up one short story of about 1300 words, and completed about 4/5 of another story for another 3500 words. As a result of this new material I am deep in the editing phase of both stories.
The real advantage of using Dragon to me will be that it will enable me to finally write a book, because in the past that kind of concentrated writing would blow out my wrists.
