I tried using a Newton back in the early 90s and...it did not work too well, except at distracting other people in class. I think the big value in managing notes with a computer is in the re-writing of paper notes after class/meeting/etc. Not only do you get an editable/searchable/printable/re-orderable version of your notes, re-entering them reinforces the memory and gives you a chance of viewing it from a perspective not rushed by the need to get something down on paper while your prof is whizzing through material. The iPad + GoodReader, Papers, iThoughts HD, and occasionally Evernote work pretty well for search and presentation, although I wish there were one good memex system.
