I find that clear notetaking is amazing in guiding discussions. Being the one who sends out the meeting summary with next actions and clarifying remarks or being able to refer back to meeting notes gives me an amazing power in making decisions or resolving disputes. Just because I'm the one who's writing stuff down, I'm somehow given the authority to say "this is what we decided at the meeting".
It varies. I'm often tinkering, which is a problem, I know. I've used a notebook, a Surface pen and One Note, a text file, scribbles on the agenda for the meeting (if there was one). It depends if it's a teleconference or not, whether my laptop battery is charged, if I can find a nice pencil, etc. etc. as well.
The summaries always go out as emails, of course, and if I paper note-take, I try to take a picture and upload it to onenote or sharepoint.
We use a record feature in Zoom for our teleconferences that we want to save, but notes are always better because you can review conclusions without the noise of skipping through discussions. It'd be amazing if there was an application that recorded meetings then summarized them.
I am not who you were asking, but I exclusively use pen and paper during meetings. I try to keep my laptop closed and transcribe action items to a personal trello board after the meeting is done.
The trello part is more recent, but I have notebooks going back to my first internship in 2012(which I know isn't that long for most here). It's pretty interesting to see old notes I took and the problems I had at the time.
I've found that the more attention I pay to my notes, the better I recall the topic at hand even without referring to the notes I've taken.
As a result I exclusively use pen-and-paper for meetings. I also started using fountain pens about two years ago and the discipline required to write well, especially with vintage flexible nib pens, helps keep me focused on note-taking.
