Yeah I have the same concern, I myself cannot answer this though. I will probably have to make the switch when I start school. Multiple people have stated using notability for their power points so that everything stays on their computer (I haven't used it myself, I did experiment with pearnote and it was pretty cool how it syncs what I type with the lecture). I believe the application notability allows for one to write on the ppt (if someone on can confirm).
I also am a pen and paper type person, because I could take all my notes and spread it on the table versus having it clumped up on computer. It will be hard getting used to keeping all my notes on the computer. I do believe that it helps because you can use word search instead of flipping through all the powerpoint pages when you look up a certain topic. There are still those who use pen and pencil. One of the residents had stated in another thread that writing it is one of the best forms of recall/retention when compared to highlighting, rereading, and typing (I do believe this myself). So I think it will be a matter of feeling it out which method works best for us when we start.
