Pilot, I think there is a third option. I always found my students struggled keeping up in lectures with laptops, and they proved especially limiting when graphs, charts, or anything of the like were involved. Now the plus side is the convenience of storage, but the old Arturo solution is the best. That said, you could always get one of the pens you couple with special paper that let you take paper notes and they are digitized for download in the pen; I have even seen some models that would let you record audio while writing. Check them out; they are easily available and, if they work nice, give you the best of both worlds.
