I've got a question for you since you mentioned that you use it to take class notes. I have attempted this in the past and I have found it pretty hard to keep up with a professor while they talk and write things down. When it is just straight speech I am taking notes of there is no problem of course since it is just normal text. But when math starts being quickly written on a board I find it hard to keep up.
Writing out all the symbols names and getting the formatting right seems to take a fair amount of time and I typically get behind.
I have a Microsoft Surface I use for class, so what I have just switched to handwriting the notes now on the surface.
