Some people really get the idea of only handling it around the edges. Lots of other people just handle them however they want and have no problems touching the media anywhere. Especially kids, which often don't have the cleanest hands at any given moment.

Lots of kids will handle them however they want. They'll pick them up with greasy, sticky hands right on the media section. They won't necessarily care about ensuring they're properly in the drive tray. They'll jam all kinds of things into the drive slots. They'll drop them on the floor and step on them, toss them in a toy box when told to clean their room, etc.

Obviously not all kids will be this way, but many will.
