Kevin Lipe, on finding a text editor as simple and uncluttered as Word 5.1:
The truth is, there’s a solution now that’s most of the way there: Markdown and a good text editor. That’s the new Word 5.1. Think about it: a program like TextMate has almost no window chrome, and opens almost instantly. You start typing, and that’s all you have to do.
I do almost all my personal writing in Notational Velocity, formatted in Markdown. It’s a nearly perfect combination.
