While I think that cell phones have the most potential for sci-fi moments (with wifi computers being perhaps second), the most interesting thing about this phenomenon to me is how - by and large - these technological advances *don't* cause sci-fi moments.
Watch an episode of star trek (tos) and consider how the communicator is framed in the shot. When Kirk (usually) needs to make a call (sorry, communicate with the ship), a shot typically shows him pulling the communicator from his belt and then zooms in as he flips it up and says "Kirk to Enterprise." The communicator is basically given the same type of cinematic treatment that is reserved for, say, a handgun in a contemporary film: when someone uses a gun on TV or in the movies, the camera will also often focus on the drawing of the weapon, and then maybe the cocking of the weapon, and certainly the pointing or shooting of the weapon. Semiotically, this treatment is designed to front the object, to show that it is important and its use is significant.
But anyone who has been alive for the past 10 years knows that cell phones aren't used in this deliberate way at all - people use them all the time, in all sorts of inappropriate locations, and, I suspect, the most commonly communicated phrase is probably more akin to "Dude- WTF??? LOL!" than something conveying actual information. If star trek were *realistically* portraying the future, as soon as everyone beamed down, they would all immediately open their communicators and call their spouses/friends and continue whatever conversations they were having.
And of course when Spock wanted to occupy the computers memory banks, he would probably have asked it to find all of the Britney Spears/Paris Hilton videos on YouTube rather than having it compute pi to some impossible digit.
Occasionally I do have sci-fi moments, typically involving my talking car navigation system giving me directions to some place I've never been before. But more often than that, I consider how impressed the 1978 me would be with all of this futuristic technology I have now...but I have do this via mental time travel because, mostly, these items became mundane for me before there was the opportunity for sci-fi moments.
But if we develop transporters, I promise I'll be impressed by it and use it for important trips, and not just to go to the mall...
