It is very clear that this method is still in infancy and we should not be expected to be able to fully accommodate everyone right now. We are working towards a solution.
The fact the DOM is parsed regardless is not a massive issue to me, as mobile browser speed increases this will become a non issue. The issue really is the images, there needs to be some way of telling the browser to completely ignore the image on certain media types, or at least defer the load if it is not meant for this media type then load it last.
There will eventually be a standard for responsive web design but at this moment in time people are doing it the best they can with the tools they have
