After spending a long time, and trying most of the tool in this thread, I now use gDocs for notes, together with syncdocs. The interface is better (smooth scroll, highlights all search matches, default shortcuts are good), the features are better (change tracking, autosaving, trully excellent collaboration), and it opens faster than most tools here, simply by using the 'save as shortcut' feature in chrome.
Syncdocs is great too. If someone edits a doc online, and you open the .doc in your hard drive, even offline, with word, you see the 'track changes.' Genious.
The only thing I don't like is the lack of drag and drop for pictures, and the delays going from files to the 'file manager' view. First time a web app beats a desktop app, in a category that is incredibly competitive.
I would not use gdocs instead of word for long docs, though. For notes, it's perfect.
