laptop definitely
but DON'T take it to class!!! people will look at you like you have 4 heads and will talk trash.
if you're that worried about your notes, buy a little tape recorder and bring it with you. but i even doubt you'd need that.
don't worry, you'll do great!
**edited to add**
also, if i were in class with someone who was typing and typing away on a computer while i was trying to pay attention, you better believe i would complain to the professor or a higher up. (i HATE the sound of a keyboard!
)
