its solving a completely different problem. you could very much want a different `*-action` of input on something like a trackpad than you would a mouse (e.g. locking panning or scrolling) and both would be `fine`. Not to mention the idea that other potential pointer types like dials don't fit into either `fine` or `coarse`.

> media(pointer-type: touch) will destroy any purpose of @​media(pointer: coarse).

firmly disagree. even if it did, a more useful interface shouldn't be stopped because a lesser one already exists.

> Also problem here is to ably 2 different pointer-actions (one per pen, other per touch) at the same time. 

thats not a problem? you can do that today

@media (min-width: 500px) {
  background: blue

@media (width: 500px) {
  background: red

both will apply at 500px wide, and if they interfere with one another source order precedence exists.

> Do you mean that media query will be automatically applied when one type of a pointer is used?

yep, just like :hover and :selected pseudo selectors, they apply based on state of the element.

> What about 2 at the same time?

see above
