I just used Google Docs, but I type very fast. I'm not entirely sure, but I think I have about a WPM of about 130. I managed with just typing things as they happened, and using the shortcuts to enter LateX formulas. I didn't encounter a lot of diagrams or other things that needed drawing during my studies, but usually kept a notebook nearby just in case.
