I read the question differently—that for any use case of requiring or preferring business text in all capitals, it needn't be entered directly by the user through a keyboard toggle state, but rather we are in a era when the system displays the text in all caps via display styling—because the business need of all caps is for a person to see it in all caps, rather than the data entry user choosing to do so (or not) directly into the database. For legacy systems requiring the data in the database itself to be the caps version, there are other methods as suitable to toggling that keyboard state but "out of the way" for other use cases.

Professional UI/UX designers do exist. We are ergonomists, and human factors people, with actual basis in science—and some of us used to work on open source projects. We don't anymore for other reasons other than we don't exist.

Laptops can improve in the area of "real-word" use: can withstand a reasonable drop and an occasional spilled drink—without the "ruggedized" "rubber brick" solution.

I'd mod this as +1 insightful. The force of "scratch an itch" that drives open source development is the principle of "hell hath no fury like a geek who's been mildly inconvenienced."

+1 for a reference to Edward Tufte regarding visual interpretation.
