In my last post I created a poll to get an idea of the extent of migration to open source GIS on the desktop. The results indicated that nearly 50% of the people using open source GIS were still using their proprietary software as well. You can view the results of the poll using the Polls Archive link below the current poll.

This leads one to wonder if it is the state of the open source software or other reasons that prevent a full migration. Take a look at the poll (right margin) and if you are a partial adopter, please vote or post a comment on what's holding you back.
