I don't know too much about Emacs' org-mode, but it looks like this is org-mode on paper. :)
Running emacs on a tablet might alleviate this a bit (if you've got it flat on the table in front of you, at least people can see you're taking notes and not emailing / chatting). However, getting emacs / org-mode on my Android tablet has proven a bit challenging.
For meeting minutes that I need to take handwritten notes, I always put them in org-mode.
Would be interesting if there was a nice script to capture a BulletJournal spread and translate it to an org-mode entry...
