Here is a link to a word processor I found over at Sourceforge. It seems to rely on Java, so I don't know if it will work on a portable drive. It says tht it is OS independent, so it should work on Windows. I don't know much about it, but it might work. http://sourceforge.net/projects/lexi
Like you mentioned, it requires the java runtimes, which are sometimes hard to come by. AbiWord or OpenOffice are definately the way to go when it comes to open source Word processors.

You are absolutely right, I was just trying to get some fresh blood in the word processor section.
