Designers/developers other than and including those at Apple have used skeuomorphism for this very reason. You want people to know where to drop files, you show them an image of a floppy or a folder. Want to print, click the printer icon. Want to unlock your phone, slide it unlocked. Using physical analogs has LONG been common. The other day I used ProComm (yeah, I know, right!?). To close the connection, I clicked the phone icon and it animated showing the phone being placed back on the hook.
