I used OneNote for my criminal law class I took in the summer.
I didn't do the class exactly correct (didn't start my outline until the reading period at the end, but you can get away with that if you only have one class), but OneNote worked excellently for me.
I just made case briefs in OneNote than wrote the outlines on a seperate page. Here's my idea for how I'm going to reorganize for the fall semester.
Class name (folder)
- Syllabus, Due Dates, Overview
- Briefs and Class Notes (section)
--Briefs will be on pages, title the same as the topic of the cases, with class notes on the subpage. There will be a new page or subpage for each day.
-- One page for each topic.
The best way to print is use the Send to Microsoft Word command (File->Send To...->Microsoft Office Word). To share notes with people, you can e-mail right from OneNote, and it displays the notes as HTML (File->Send To...->E-mail Recipient). Note that both of these require the rest of Microsoft Office, so they don't work with OpenOffice or Thunderbird.
Once you send the outline to Word, you can mark it up with page numbers of cases and of other portions of the outline, since OneNote does not make new "pages" as you go along. I really think the search function of OneNote is great because during class you can type in a case name or citation instantly and get to your brief, and even see other cases where it was mentioned.
