Very few students in my son's class ever took notes on a computer.
You might consider this. Get some laptop and then get auxiliaries that may help. A full size keyboard and a mouse are nice. Also, you may find that a wide-screen monitor is helpful for your drawings. With a laptop-size screen, sometimes you can't see your whole drawing at once, or else the actual drawing is really small because of your tool bars.
Some programs that I know my son made use of were Matlab, Maple, CADD and Solidworks. Make sure your purchased machine can handle these. In fact, your school probably has recommendations...check with them.
