And neither is battery power. A terminal application is supposed to be small, and next to invisible in terms of resources required. If it isn't, it will be uninstalled.
According to whom? The terminal gods?
According to wikipedia:
"A terminal emulator, terminal application, or term, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces."
I don't see anything in there about "invisible in terms of resources required"
In that strictest sense of the word, even an RDP client onto a windows desktop is a "terminal".
As the article points out itself however: The colloquial semantic meaning of the word, aka. what is usually meant by it, is TEXT TERMINAL.
And btw.: Even for a fully featured RDP client, I wouldn't accept a size of 200+MB. The one I use at work is barely 4MB.
Given it won't run on my Raspi. But there can still be value in things that don't run on micro computers.
