I think for a specific set of commands, such as showing a list of local starbases; in the same way you would select a menu option in word to create a mail merge then the idea of a console with a set of function buttons becomes useful. As soon as you're in a program with a specific function, then toolbar shortcuts can become your new keyboard.
Current computers serve more than one purpose, where a star trek terminal has a specific requirement. Also, the data on this planet isn't organised in a well enough fashion that we can provide a single form of interacting with it with what amounts to shortcuts.
As soon as information becomes uniformly organised (and the extremely unlikely concept that a computer has a requirement for a single set of tasks ) then we'll start seeing changes on a commercial scale.
But I still dain't think it'll happen...
