I'm back to paper for several reasons. First, in our office we get a lot of paper attached to things that come in the courier (routing slips) and I throw those in a tray, pull them out for various notes. I feel virtuous. Second, my wife gave me some really nice fountain pens as gifts and I enjoy writing with them (kinesthetic pleasure.) Third, I found it WAY too easy to load up my Task list in outlook and overwhelmed myself. On paper, writing a task list, you really can see immediately if it's getting out of control.
I collect to paper or in my car to an Olympus voice recorder. I use Dragon Dictate to transcribe it.
