"Minority Report" is the first thing, that comes to my mind. But, of course, there are so many other SF examples... as well as many CSI-like-absolutely-no-SF-movies etc.
Why? What is the reason for telling people, that using screens, viewports etc. with transparent background and all the things seeing behind is useful, when it isn't useful at all. It makes your eyes tired and it makes you less focused to details, disoriented etc.
Is there any SF book or movie, that in particular addresses this topic -- i.e. contains reasonable explanation, why such screens are used or an attempt to prove, that they're better than nowadays non-transparent screens?
