*We've discussed how your goal of finding out what kind of device is being used is not well-served by option #2. What are your other use-cases?* That was far from conclusive. Without UA sniffing or developing an entirely new technology, #2 is probably your best bet for delivering styles specific to a device class. It is certainly better than the current arbitrary pixel ratio, which is a disadvantageous circumstance to be in at all. *If #3 is totally arbitrary at the whim of the device vendor, how can authors use it at all?* It is useful when authors would like to adapt a layout according to what hardware vendors believe are the most appropriate and likely viewing circumstances. You can consider this similar to using the default value of 1 REM for measurement, only with a deeper correspondence to physical space. -Brian On Thu, Oct 27, 2011 at 5:20 PM, Robert O'Callahan <robert@ocallahan.org>wrote: > On Fri, Oct 28, 2011 at 4:55 AM, Brian Blakely <anewpage.media@gmail.com>wrote: > >> 3 means of defining an inch have have been discussed: >> >> 1.
