Yeah, they were pretty close on a lot of that, even if they didn't quite get the terminology or exact mechanism right.
Personally, I'm glad videophones never took off. There is no way I want to have to look at someone every time I use the phone. I'll Skype when I feel like it, that's it.
Videophones are a sci-fi conceit that isn't really based on any real need in the market or technology. They've been feasible for decades, but the market doesn't exist because nobody has any particular desire or need to sit there and stare at an image on a video screen while they're talking to them. If you WANT to see who you're talking to, you talk face to face anyway; if you just want to exchange information conveniently without having to arrange a meeting, most people would prefer to text each other.
Here's a question: how come nobody predicted the municipal/social menace that is texting while driving? Could it be that science fiction writers the world over never imagined that their fellow human beings could possibly be that stupid?
Yeah, there's just no market need for videophones, as you said. Live streaming audio/video for prurient interests, though?

As for texting while driving, I think science fiction generally saw communication technology as becoming more featureful and complex, not less. Let's face it, texting is pretty low-tech compared to everything else we've got today. But it does have certain advantages: it can be deferred until you have time to read/respond, it's less work than sending an email on modern phones, and "text speak" has evolved so it's an efficient communications medium.
I think your hypothesis is right: who imagined people could be quite so stupid? We're supposed to be getting smarter, not dumber.
