Yeah...TOS had communicators which had a single, plot-driving function; they communicated. The ship's computer was static and reactive; you addressed questions to it. It didn't anticipate or extrapolate. TNG advanced the mechanism of the communicator a bit in that it no longer had to be hauled around but was worn. It still just communicated, and to get data in and out of the engines, the sensors, or the computer, you had to go to either a station or a specific device (a PADD, etc.) There is no sense there of where the cell phone is evolving; to have innate computational power, to contain diaries and other data base, and to be seamless connected (eventually, that is!) to all the other data bases and information systems. Your modern cop has instant access in their car to license data bases -- they don't call them in, they interact with the data base. There are theaters where the lighting systems are on cable and can be run by a guy on a laptop in a hotel room. And the idea of the static computer that one addresses a problem to...we have micros running in toasters, cars, they are building them into the support girders of bridges!
