Ability to know equipment well enough to lecture by showing equations simply with a pen and paper goes a lot further than running around with a laptop demonstration sometimes.
People are more impressed with knowledge we are able to impart without relying on flip-boards visual aids.

That is true.
In the last few years I have also moved into the commercial area.
I usually explain without presentation. I use day-to-day examples to explain technical concepts and I am doing well with this way of working.
Thanks for your support and comments.

Not having to rely on anything extra except your knowledge, conversing in such a way people do understand, keeps you more on track and in command of the discussion.
