When I moved from Wappingers Falls, NY to Austin, TX in 1980, I was moving from one IBM location to another. I was supposed to have the position of Technology Manager for the IBM Austin site. I didn't find out until I got there, that the position was filled. So, I had some time to get acquainted with the technology important to the site. Austin had been a second source manufacturing facility for typewriters and was transitioning into electronic hardware software systems, then in the form of word processors.
I did a research project on the key technologies important to the future of systems similar to word processors and concluded that they were all going to merge - audio, visual, text, electronic communications, and all digital. When I tried to communicate that to Austin IBM executives, I was met with blank stares. I might as well have been from Mars.
The iPhone has finally done just that. And, there's still more to come. Watch what happens when TV goes all digital.
