It seems that the UI shown in games and movies is meant more to quickly show the viewer what the screen is trying to say more than it is supposed to be usable to the person. That's why you always see such big fonts and simplified diagrams. It would seem to me that this is generally inefficient because it means you must constantly be switching between views if you want to see more than a giant number a progress bar. Furthermore, there's a certain one-upsmanship in Hollywood in trying to show how advanced a society is by how many increasingly complicated gestures one has to perform to use the interface. Something tells me that a Minority Report style interface is more tiring and over the long run than a keyboard. Heck, there were people complaining that the Wii has similar issues with extended play of all these waggle games.
