I don't intend to make money with it, but yeah I found it to be pretty useful if I want to give quick-and-dirty presentations to other engineers or technical folks. It basically allows me to switch between the presentation and a demo (running in the console) more seamlessly.
For my particular use case: I work remotely and we use video conferencing all the time. Our video conferencing software allows you share a single screen which is neat, but annoying if you need to switch between a browser (or PDF viewer) and the terminal.
I wouldn't use it for "proper" presentations, or stuff that needs a lot of math (LaTeX beamer comes to mind for that).
