Just to toot my own horn a little, I have an article on Free Software for Boaters (with lots of links and resources) over on Mad Mariner as the "lead article" today.
Covers software for everyday life (word processing, graphics, etc.) that you might not be aware of that is available for free or very little cost that compares well with many of the commercial offerings.
Limited time trial subscriptions are available for no cost, so you can try them out!
For full disclosure, I write some paid articles (obviously) for Mad Marinerâ„¢.
