BigZee writes "For many years, I've used a page-a-day diary as both a planner and a method for taking notes. While not perfect, it's proven to be an approach that's worked fairly well for me. Conscious of the limitations, I want this to become more electronic. In principle, I want to be able to use my Nexus 7 for this function. There are some limitations: My workplace uses MS Outlook. However, I am not able to use Evernote (or similar) on my workplace machine. This limits possible integration along the lines proposed with GTD. What I want is to be able to take notes that are organized by date as well as being integrated to a calendar (preferably Google). Additionally, I want to be able to prioritize my work along lines similar to GTD. I'm not averse to spending money for the right software but prefer to use free software where possible. Can anyone suggest what could be used?" The above-linked Wikipedia page lists some relevant Free software as well as closed-source options. If you use such organizing software, though, how do you use it, and how well do you find it works?
