I started using org-mode seriously a couple of months ago. Nowadays my entire GTD system is there, plus my calendar (synced with google's), book notes, drafts, project plans, you name :)<p>With orgzly on my android, I can access and add/edit stuff everywhere. I even have widgets with my agenda as well, instead of the google calendar one.<p>org-mode is super underrated, more people should try it out :)
