Re: [csswg-drafts] [mediaqueries] Consider exposing "mobileness" as a media query (#7696)

What’s a _mobile_ device anyway? Is it the same as a _moving_ or _movable_ device? 

- Is a laptop mobile, if you only ever use it on your desk?
- Does it become mobile when you are using it while riding a train at 300 km/h or on board a plane at 800 km/h?
- Is a car entertainment system or ”GPS“ navigation system mobile when used by the driver at 50 or 100 km/h?
- Does this change while standing in a parking lot?
- Is it different for the screens for passengers sitting in the backseats?
- Is a phone’s mobileness different for when you are sitting at a bench or walking down a street at 5 km/h?
- Does a tablet become less mobile when its smart cover is folded as a stand or when a physical keyboard gets attached to it?

For several of those scenarios, user distraction and focus are relevant factors while designing user interfaces. They are different from whether direct interaction with a touchscreen is possible. They are also different from how big the screen is or what is its orientation and how far away it is from the user’s eyes. Several mobile devices do not even have a screen, but are audio-only (and hardly any of them consider CSS).
