I am old school and use pen and paper, but I'm also older and didn't have a laptop in college, unlike a lot of my classmates, so it's more familar/comfortable for me. Also we have wireless internet access in our classroom and I am just not disciplined enough not to IM or check email if I have my laptop on. I know from looking around that half my class plays solitaire or surfs the Internet during class. By forcing myself to take notes by hand I find myself really focusing on what the professor says and being more engaged in the discussion.
Umm... for all of you who play solitare or search the web during class - THANK YOU for making it easier for me to be in the top 10% of my class! There is no way I would be paying all of this money for a legal education to waste a second of it. It depends on the class for me. If it's a heavy notetaking class, I use my laptop. If the prof. is more interactive, I sometimes take notes by hand and transfer them to the laptop later. Come exam time, there is NO WAY that I would handwrite. I type 120 words/minute and I can get double or triple the info down vs. someone who is handwriting. But hey, don't listen. I like being in the top of the class.
