Ross Carter of Cocomot has a pretty cool new word processor, Pagehand, in the works. It reads and writes in PDF format, so you don't have to think twice about sending a document to anyone; they may not be able to edit it -- depending on the software they're running -- but you're pretty much guaranteed they'll be able to see it exactly the way you did on your screen. That's important because Pagehand's features are heavily geared towards making correct and beautiful typography easy for everyone, and providing many of the advanced features you'd only find in applications such as InDesign or Quark. Ross demoed the word processor for me at WWDC. Check out the video for a brief overview of the application and some of the philosophy behind it. While it hasn't been "officially" released yet, it's available for download and trial in its 1.0 incarnation.
