Not the most feature-rich online word processor, but definitely the most beautiful. Its features include tables, lists/bullets, images, comments, headers/footers, spell checker (in multiple languages), links, and the basic processing options such as font style, alignment, etc. I know Google Docs has more features, but the interface in Buzzword is responsive and simply a joy to use.

Buzzword is really good. It has a slick interface and is all online. Plus, you can export in .pdf and OpenDocument formats. You can import too if you don't want to copy+paste. Its awesome. =]
