I would want either odt or doc compatibility so that I could share with other people at a moments notice.
To give you a better idea of what I am looking for, I am sort of looking for a replacement of pages on OSX. I want to just be able to go full screen, have basic functionality, and have it look somewhat nice so that I do not strain my eyes.
And that is what this really comes down to. I want to avoid eye strains as much as possible because I am usually in front of a computer 12+ hours a day.
