Except you don't have to make two versions of a page.

Preferably websites do that for you, in what is known as a "mobile site". In addition mobile sites have links to the full site, which I'd imagine is how most of your mobile users browse wikis with; trying to emulate desktops, not the other way around.

And the solution was, at least comparatively, whatever you were doing before this update.
