A word of caution for those of you who are considering typing: this is law school, not stenographer school. What do you mean by that, you ask. It's easy for people to type literally every word that comes out of the professors mouth in hopes that regurgitating a lecture on an exam will get you a good grade. Wrong. A large part of law school is learning how to decipher the important from the superfluous, the need-to-know from the bull. While it's still possible, it's incredibly hard to hand-write an entire lecture vis-a-vis typing it.
On another note, one reason I favor handwriting over typing is for outlining purposes. Instead of copy and pasting my lecture notes from Word or OneNote or whatever, I have to re-read my handwritten notes and then type them into my computer. Not only does this process reinforce what I've learned from class, but it immediately helps me identify areas of confusion or issues needing clarification.
Take that for what it's worth. Remember: there is no cookie-cutter way to law school - you need to find your own niche in nearly everything you do, including note-taking. I just provided my testimony as a way for you to consider a side to which you may previously have not been privy.
