Kind of depends. If I'm in a meeting that I will be using my laptop, I can take notes in my Emacs-OrgMode running "brain". This does not happen incredibly often, but it happens. If not, I have a portfolio with a pad of paper that I carry around that I take notes on. I've gotten to where I can write pretty fast, but if anyone has to read my notes, they will have trouble with some of them (though it's a minority). I write in all capital letters. I can read everything that way, but some of my letter constructions slur together. I know to look for it. Others don't. It ends up being about 80% hand-written and 20% electronic. Of the 80%, probably half gets transcribed later into the Emacs-OrgMode files. These are stored on Dropbox, just in case...
