What should a student install on his laptop?
You may want to try EverNote for taking notes in class (link). I use it at work but I wish I would have used this in class. You just type in your notes and it automatically saves it. You tag the notes, organize them, add clipping from firefox and IE. The free version has all of these features, if your laptop turns into a notepad you can buy the full version which adds “Handwriting and Shape recognition, Advanced Note Recognition (ANR) and Ink-Note Search.” It is very highly recommended by me.
