Which is one of the strongest selling points of Emacs and Vim. Ubiquitous doesn't equate to web based; there are plenty of native apps that are ubiquitous, and on top of that they don't require a constant network connection, or that the server is up. It also seems to me that if you have the source, you can get the software running just about anywhere.

I don't think we disagree. It's just that on the web ubiquity is free.
