FocusWriter is a simple, distraction-free writing environment. It utilizes a hide-away interface that you access by moving your mouse to the edges of the screen, allowing the program to have a familiar look and feel to it while still getting out of the way so that you can immerse yourself in your work. It's available for Linux, Windows, and Mac OS X, and has been translated into many different languages.
There is nothing better than finding an unexpected five minute window open up that can be spent enjoying a good book.
The key to the unexpected free time scenario I mentioned is that I must have the reader with me at all times. My experience has taught me that the only way I can guarantee always having the reader with me is if it lives in my cell phone.
in the first two weeks of iPhone ownership I had read six books on it
any comporomises you might be making due to the small screen on your phone are more than met by the joys of finding time to read you would otherwise miss.
