As for teleprompter I don't know what the big deal is there, teleprompters are used all the time so the speaker can look directly at the audience/camera and doesn't have to look down at there notes, A speech is prepared in advance so what needs to be said is written so it's got a structure, concise and clear,
Some how you think the way Trump speaks going off script is a good thing. If you look at transcripts of Trumps speeches you will see that there is no structure, he rambles, repeats himself, its inconsistent and all over the place.
I'f I ever did a speech like that at Uni I would get a big fat fail
