I seriously think that good handwriting recognition is not all that necessary. What IS needed is a really good app for notetaking when you recognize your OWN handwriting. The best app now for that is probably Xournal; the only problem if you are taking notes quickly in a class would be that it would be too much trouble to keep starting a new page. You should just have an extremely long page to work with so you can take an hour or so's worth of notes without starting a new page.

Then, after the lecture is over , you can reread your notes, organize them better, and put them in Notecase or something if you want to make them permanent.
