Oh, that should be the default! Since the day the fist laptop came that shows a 2nd screen (instead of a copy), that should be standard issue with presentation software.

Well, yeah. But using them so that the speech still sounds fresh really requires one to know the speech almost by heart. And a lot of practicing each speech, with live assistants.

The next step (down) from that is the class where the professor wrote the text book. That's a bad thing because if you don't understand the lecture, the book won't help

At the other end, if the professor *only* lectures on what's in the book, what are they being paid for? Just talking? Better would be for the professor to lecture on application, the what/why (and not the how), how ideas are related, anecdotes and the like.

NO! It takes about 10 (or 100) times a much work to get a speech down word for word. I just want to have a better handle on context and more notes than I get with the setups I've used.

My Physics courses were like this, and it was incredibly frustrating.  I think it was probably the reason that Physics at my Uni was reputed to be so difficult.

Books are meant to be read before taking the lesson.
Among other things, a teacher in science/technical fields can:
- help students understand difficult concepts;
- give problems that require the student to invent some new idea or be creative;
- answer student questions.

Exactly my feelings.  Reading the book at one's own pace is a good way to get all the nitty-gritty technical details down.  What lecture should be for is understanding the stuff at a higher level.  This includes asking questions, discussions, broad overviews to help students see the forest instead of just the trees, etc.  I tend to feel that huge lecture hall lectures, were any interactiveness is impractical, are largely a waste of time unless the lecturer is exceptionally engaging and/or you have enough background in the topic already that you're mostly interested in understanding another point of view on the subject rather than learning it for the first time.

I take notes so that I will remember what was said five minutes prior. I never review notes after the lecture, but during, it helps me work through the examples given, at my own rate, and change the notation used.

For example, I was at a compilers lecture and took twenty minutes to understand a parsing example. Then I changed the notation slightly in my notes (the professor was using states 1, 2, 3, ... and rules 1, 2, 3, ...; I changed the states to be S1, S2, S3, ... and the rules to be R1, R2, R3, ...) and suddenly everything became a lot clearer.

My College Physics teacher wrote our book. I never found it good. But then, he was a bodybuilder. Once he had connected a heavy iron core coil in series with a lamp and a battery. And he had an iron anchor, which he removed from the coil. The lamp blew, and he said "gee, what a coincidence". I remarked dryly, "that's what you get for removing the anchor". From that day on, he hated me. Later in a big exam, he came to my desk and said "well, einstein, just see to it that you get full points". Thaks a lot.

The director was pulling his hair because I couldn't remember 15 secs of lines at a time. If I make a presentation, I simply have to get familiar with the subject, and then have the slides, like, be my cheat sheet. I always envied the guys (often sales reps, or evangelists), who did the same thing word-for-word, even if I saw them again after six months.

If you haven't before, check out presenter mode in powerpoint.  It's pretty much what you just described.  Only takes two screens, one the projector and the other your laptop's display.  The laptop display has 3 panes: a sliding window of the slides; the current slide; and your notes.
