Org-mode is great, but I think there's validity to his point that taking notes on a laptop during meetings (especially with external people) can come across as rude.

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.
