I historically used notebooks, then tried Rocket Books (the ones that you take a photo in an app and then either wipe clean or microwave to reset them). I found taking the photo was too time-consuming, and I also went through an awful lot of pages sometimes, which meant I was needing to take pictures so I could have some new blank pages while I was still in the middle of a conference.
I went back to notebooks (much better quality), but then wanted to scan everything and label it so it was archived against each client, which just takes a ridiculous amount of time. Otherwise, you don't have access to the old notes, which are still relevant and needed, so I found myself carrying around two notebooks most of the time: the current and the past.
I tried using my iPad, but the screen brightness distracted me and others in the meeting so it really wasn't ideal. I also found that if I needed to write on it standing up, it was very awkward, and the screen was slippery. Also, because you could see your emails, someone would say, "Oh, can you just look this up or check the calendar on this date?"
When I got the reMarkable 2 and started using it, nobody noticed at first, which was exactly what I wanted. Personally, I pay the Connect subscription which is £40 a year as I want my notes backed up. Otherwise, if you lose the Remarkable, it's the same as losing your notepad, everything is gone. I really appreciate the sync function, my notes sync to my PC, my laptop, and my mobile. I can type text into the reMarkable on any of those devices if I need to, and sync it back to the actual reMarkable "notebook". I'm lucky work paid for it, but with hindsight and having used it for several years, I would buy it myself if I needed to now, because the convenience and efficiency it's given me has saved hundreds of hours. There's nothing like being able to look back and tell somebody on this date they said XYZ. I do write lists in it, and Claude is pretty good at deciphering my handwriting to turn them into actions if I give it a screenshot, but I don't bother with turning my writing into text. It's not generally neat enough, and the notes are for me.
I know the best way for me to remember things is to write them down. I often can tell someone exactly where I was when I wrote something and which part of the page it was on, so the reMarkable works really well for me to keep that memory link going.
For those talking about recording meetings or typing: recording, you obviously need permission from the other participants. In my experience, people generally talk much more freely when they don't think they're being recorded. Typing: I can type very well, but again, it's a distraction. You turn up to a meeting, you potentially need power, the screen can become a barrier between you and the outside world, and, again, in my experience, it's really easy to get distracted. 90% of my meetings are in person, so perhaps if they were online, I would think differently.
