It's not just about looking cool. It's tough to make a film where characters are interacting with a screen or drawing on a whiteboard because the director usually wants to show the actor's face along with the screen so we can see their reactions. Which is why so often you see shows where actors draw on clear glass whiteboards even though no real office would ever have them. Likewise transparent phones: It's an unrealistic moviemaking concession that audiences mostly tolerate.
