if the person is not blind (in which case the gesture systems will move focus item by item) 
and the person is also not using a keyboard -- what do they need the skip link for? 

If they are using a touch screen as a touch screen there is no need for a skip link - is there?

With the proliferation of tablets, smart-phones and other touch-screen devices, it makes more sense to have them always visible now.

I expect that within a decade we will have some new techniques that may require little or no effort on the part of authors.  But for now skip links are a common technique.    And having them visible is good because people who navigate by keyboard need them too.   But they are not required specifically and visibility is also not required.  Best thing to do is just read the SC carefully.  If it doesnít specifically require something -- it isn't required.    Almost always the SC requires that something be possible but does not require a specific way to achieve it.
