Open Source software is no longer just for geeks. Open Source can offer a tremendous marketing tool when properly implemented. For instance, take Xandros Linux as an example. They offer their a completely ready to go version of their OS at no charge whatsoever. The more advanced business class version, offers more features and is available for a very reasonable amount of money. When they first announced that they were offering a ready to install free version of their OS, the press went nuts! There were press releases and news stories all over the place.

By allowing your customers to have a free version of your software, you will remain fresh in their minds when they decide that that they are ready for something a little meatier.
