For content editors, don't you want a stable system and easy to use interface that just works? Low latency, that doesn't hang every so often when you click save?
Perfect for bloggers who are always on the go. Don't you prefer to write content while you are in the airplane instead of updating it while partially enjoying your meal at your next dream destination ?
