In the sprawl trilogy, the big black character that gives the hero his mission he's using a fax machine embedded in the seat of the cab where they first met. A fax machine. That spit out paper with ink on it. It was already old tech and weird when I first read the book 4 years after the published date.
In Dune, they are reading texts on ridulian crystal. When I read it in the 90's I thought "must be some kind of indestructible paper". Herbert didn't describe the item which incidentally allowed the 2000's SciFi series to show ridulian crystal as some kind of a very thin and intelligent screen reader.
Ridulian crystal will never age but FAX machine, e-mail[0], etc will and they will pull you out of that suspension of disbelief state.
With that said, and for what it's worth, I prefer Gibson to Herbert and I dislike made-up name such as `ridulian system`.
