That analogy doesn't hold well though, because calculators were (at least eventually) better at everything a slide rule could do. This article is predicated on the idea that this doesn't hold for CLI->GUI. You may disagree, but it's not obviously false.

Yes, I caught the drift of the article. I think a better title might have been "Teletype Emulation Strategies to Break Your Dependence on the GUI"

If we are going there, why not "Teletype Emulation Strategies to Break Your Dependence on Limited Desktop Metaphor" ?

Or "airplane seat" metaphor as Frederick P. Brooks, Jr. said.
