Speaking as a huge fan of the Newton MP 2000 (which I kept using for years after the Newton was cancelled):
1) You can search your meeting notes. I had four or five years of meeting notes that could be instantly (well, by late 90s standards of "instantly") searched.
2) You could point it at any IRDA printer and just print stuff. (I was astonished by this when I discovered it worked, because the first IRDA printer I got was made long after the Newton was cancelled.)
In contrast to this, most of my paper notes (and I've gone back to paper) end up being lost, and those that aren't lost are horribly disorganized. Generally, the half life of paper notes -- for me -- is perhaps a month.
