We used to have two toggles for delivery settings (photo prints/email on/off-- coded as checkboxes) on Picplum and we quickly learned that people tried to drag them as well. So we reverted back to plain checkboxes. Sometimes just because you can do something (and it's pretty) doesn't mean it's usable.

I agree. If you're going for skeuomorphism you should take it all the way in terms of manipulating 3D elements.

yeah, i did the same thing. maybe have both options available, or even when someone visits the site on a mobile device then the click n drag feature is enabled.

You can drag it, you just can't end the drag motion outside of the dongle area. Took me a few tries to figure that out myself.
