Biggest problem for this issue today is: kids don't know what a command line is, and are unfamiliar with the classic "terminal" interface.

When teaching an intro to programming, my curriculum still uses this "command shell" form. Of late, nigh unto no students have seen it, and I have to teach it as a new concept - a problem as it's more obsolete than new. Soon we'll have to give up on it as a starting point, saving it for more advanced students. GUIs rule now; beginners don't grok a text prompt.
