I'll be using both my laptop, iPad, and pen/paper. I'm typing outlines for chapters this summer- we had required reading for the summer before we start, so if they actually get lectured or reviewed, I'll be able to add specific notes from the prof. I also bought the eBook version of my Fundamentals book on my iPad, that way if I don't want to carry my 8+ lb book every day, I'll be able to read on my iPad and then go back and outline. Writing also helps me retain information, and if they give handouts, I'll be able to write down information and go back and add it to my outlines.
For me it depends... iPad with keyboard (essentially a laptop) and I use the voice recorder app at the same time while taking notes, but if I'm in a class that is covering something I'm confident in, then it's just voice recorder and pen/paper for key notes... Hey, can anyone vouch for a good note taking app? I just use "Notes", but I've heard about Evernote, what is it exactly??
I think I'm going to keep it old school. With a laptop, you can't make yourself little side notes or little stars/asterisks/etc to remind you that 'HEY this is on the exam' or 'HEY you might wanna know this'. Plus, with pen and paper, you can use highlighters, different colored pens, markers, sticky notes, and basically anything and everything to help you retain information. I usually wrote all over the page and it looks like a rainbow by the time class is over. I don't know if I'm the only one but it is super helpful!
