As I said, there's "cm", "mm", "in" and "pt", which don't have that kind of ambiguity (I mean, their name is clearly absolute), and can be used when an absolute length is wanted. But implementation-wise they probably have the same problems as "px".

You are right that it doesn't always work due to the fact it is a rather new attempt at a solution and as I mentioned is is part of the HTML5 initiative so is not applicable to older devices. At some point you just have to consider old devices for what they are. Amazon has demonstrated that you can migrate from an old mobi format that is not even HTML4 compliant to a HTML5 by tolerating two displays that are not the same quality. The new px solution has the advantage that older devices continue to work even though the screen size isn't quite the same. And you are right, in practice the real values of cm, mm, in, and pt aren't not properly supported either and probable will never be.
