Insightfull inspection, do you agree?

(1) Users actually find typing stuff in a lot easier than clicking things. This one surprised me a lot. I have got people to use ping, ipconfig, winver, netsh etc. with very little difficultly. In constrast, common gui elements like radio buttons, drop downs, menus, right-click menus etc. have to be explained fairly regularly. I think this is related to the "exactness" of typing, versus the ambiguity of clicking something.
