Where will we be ten years from now? CRT's will be a thing of the past, multimedia will no longer be a buzzword, pen-based and voice input will be everywhere, and university students will still be editing with emacs. Pens and touchscreens are too low-bandwidth for real interaction; voice will probably also turn out to be inadequate. (Anyway, who would want to work in an environment surrounded by people talking to their computers?) Mice are sure to be with us a while longer, so we should learn how to use them well.
