I forgot who, but they convinced me the web is occupying the areas the OSes failed to do: interoperable app platform, easy and accessible UI and programming, fine grained access to files (a /home/x is free for all for all processes) etc. Hence the browser will gain features so that few vendors can keep up. Of course, not justifying 2M bundle for a poem page or ad network behavior.
