Theres really good and bad things to typing notes up. The good side is theres less effort when you type it, its a lot neater, very easy to edit and much more legible. But the practice in writing the material is gone! So really its personal preference, if you can write like the wind and not get a sore hand then why not go for the typing.
A classmate of mine types up his notes first, and hand writes a copy after. Thats doubling the work really, the printed copy he keeps to study with, and hands in the written copy like the rest of us.
