Do We Live in a Science Fiction World?

One of my favorite scenes from David Lynch 1984 production of Frank Herbert's novel Dune is in the beginning of the movie when Paul Atreides, the protagonist, looks at a book-sized computer. It has a video screen that teaches him (and provides exposition to the viewer).  Check this out.

Here's the unit.

In it you can scan libraries of information. In this case, Paul is looking up different planets.

Look, you can enter search terms.

You can even watch videos on it! 

Does this device, or at least it's concept, look familiar?

Yup, it's an iPad. Sometimes science fiction comes true.
