My critique of Device Adaptation consists of three main themes:
- The spec does not address the actual current situation at all, while all browsers actually support my theory of the layout, visual, and ideal viewports decently, and I’ve already done the heavy lifting.
- The spec is obscure about what its most important components actually mean; I’m especially thinking of the initial and actual viewport. A simple schematic would have helped a lot here, and it’s fairly easy to produce.
- Although the spec treats relevant media queries as well as the meta viewport and the
devicePixelRatio. That latter, especially, could do with some specification.
