As a fellow writer, may I recommend Scrivener if you write fiction? There is a trial available I believe. Great program, you can organize your thoughts on notecards, and then shuffle everything around as needed.
Interesting you should mention Scrivener... I am looking at an older work of mine in it right now... I've been using it since around version .70. I don't really know how I wrote anything before it.
I've read that the full screen mode on the 11" Air and Scrivener isn't too bad of a combination...
