I really do not like to store my daily work and documents in MS Word format, nor in OpenOffice format, because those formats:
- Uses a lot more space that what is really needed
- You need to have the application installed to read them
- It is not easy to work with them on mobile devices
- The format changes over the time, and your files become obsolete
I tried to use LaTeX but it is a little bit too complicated, and it is not too easy to understand it using a simple text editor. I tried to use markdown too, but it lacks of some features I sometimes need for my documents, so, that was not an option.
MultiMarkdown, is a good option, and I have been using it to store my documents, but I see that ReStructuredText has more features and working with Pandoc, you have all bases covered.
I will be using Multimarkdown (which can also convert to PDF) and RST together to work with documents in my daily needs.
I have now installed in my Mac Multimarkdown and Pandoc, with those tools and learning MMD and RST syntax I feel I will be able to write the simple documents I need.
A bonus on working this way, is that you can use Git to version control your documents
