If you want to challenge that idea, feel free, but come up with cases where having physical measurements of the device is a bad thing or don't help to solve a layout choice problem.

One JumboTron-like display is 640x480 (using lightbulbs), and another is 1600x1200 (using LEDs). If you want to display a Web page on both, using media queries on pixels is going to be much more useful than knowing their physical size. Same thing for projectors, where the actual physical pixels might be on something the size of a postage stamp (or smaller), but it is often unknowable how far away the screen is (and thus how big the final projection is on that screen). What happens in these cases when you write a media query for your Web page about the physical size?

We've had these discussions before, ad nausium, and we resolved on them.
