Dick Tracy wrist radio (and Star Trek communicator) notwithstanding, fiction didn't really broadly embrace ubiquitous communications. I suspect part of the reason is that, as the article notes, a lot of fiction uses control of information flows as an important part of plot construction.

And, as you note, video phones were pretty universally envisioned as landline plus screen. As with many things, video has of course evolved much more organically. Initially primarily on mobile and, of course, it's exploded on notebooks/desktops in the current situation.

I have a 1986 Playboy and in the "Tech Section" there is a image of a "video phone" which was basically a landline phone setup with a tiny 5" B&W screen with an image of the person you were talking to and it was hailed as the future of communications.

Behold, the Luma Telecom Video Telephone:

Even weirder, things like this were still being marketed this century: https://www.theregister.com/2004/09/15/amstrad_e3_launch/

Well, that was 3 years before the launch of the iPhone. It totally made sense at that time.

There was a picturephone booth demonstration at the 1964 world's fair: https://ethw.org/Picturephone
