In order to resolve #32, I've modified the responsive units section.
I have not fully understood the problem up until yesterday (Thanks Marc). It is not an issue of developer convenience, but of catering for both the 1em==16px users (most of the users) and the 1em==???px users (users who have set a different default font size, or that their device did it for them).
In these cases, without em based units for art-direction, developers will have to choose between PX based MQs, resulting in text overflows, or EM based MQs, resulting in the wrong art-directed images in some cases. (possibly breaking layout or getting distorted)
We still probably need to add a figure that describes this issue.
