Practical FOSS Options (Score 1)

I use GTD and have found Thinking Rock's free version (http://www.trgtd.com.au/) to be very useful. WRT to not being able to use Evernote on your desktop, if you use Linux, you can use Everpad (http://www.makeuseof.com/tag/everpad-evernote-client-ubuntu-linux/) to sync with your tablet Evernote app. If you just need a good application to journal and tie ideas to dates, I don't think it gets any better than the RedNotebook (http://rednotebook.sourceforge.net)
