But they do provide advantages. They're *much* easier to use than current general-purpose computers. A button for every function; no funny modes in which the buttons do something else, or nothing. A display for every state variable; you don't have to click on things to make them visible. I suspect that this is not an inherent limitation of general-purpose computers, but a limitation of their current state.
