Jaap Geurts asks: "With the 3D GUI desktop around the corner, nobody seems to use or think about text based user interfaces (TUI) anymore. I know that hardware comes cheap nowadays but can the use of TUIs still be justified? I've always found that GUIs are resource hungry, generally slower and more importantly they often allow multitasking and they are very unpleasant without a mouse! What do you think about developing a (well designed) TUI for DB software (e.g Point of sale, Warehouse manager, etc)? Most current GUI metaphors can be implemented so what are the pros and cons from a user perspective?" Are there any real reasons against deploying text-based applications, today?
