I don't like the fact that we're currently doing some user agent sniffing to allow touch vs drag.
In theory click/touch should only be enough, but the dragging adds a "fun" benefit to it. It would be great if it was really just a benefit/extra instead of mutually-exclusive options.
Option 1: Show "touch-only" and switch to "drag" capabilities once there is a mousemove event.
Option 2: Enable touch & drag, have just one explanation sentence, no more sniffing or detection
Interesting discussion about this kind of situation: https://github.com/Modernizr/Modernizr/issues/869

I personally prefer Option 2.
