We don't have flying cars, but otherwise, it can be hard for science fiction to keep up with the pace of modern technology. Evan Hoovler of blastr has a list of eight technological wonders from science fiction now present in real life, such as the PADD from Star Trek, now available as the iPad:
Like modern electronics, the P.A.D.D. had its own development throughout the series. The 24th-century model was almost solely used by touching a screen. Not bad, but we're sure the Enterprise captains would've probably liked some Freecell while drifting through empty space. How about one of millions of books? The iPad incorporates modern technology into this classic sci-fi design, moving us one step closer to achieving the ultimate dream (holodeck).
