I get it…it’s hard to say something you know is incorrect, accuracy of language going to shit and other modern problems, and I feel that. I think of it as more of a “internal lighting that illuminates the device interface.” In dealing with non-technical people on a daily basis, I find it’s much more productive to allow/ignore this sort of colloquialism unless it’s that specific thing I’m trying to fix/undo/explain. I barely even flinch now when people refer to the large box on their deck as the “CPU.” ;-)
