I took all of my notes in college on a windows based tablet using OneNote. I love the notes I took, and can still occasionally refer to them over a decade after college. The writing experience on any PC based tablet is going to suck compared to the One Note.

I really hope that in the future we just get OneNote access on the supernote, but until then it doesn't have the features.

That said, writing math is as easy as writing it in a notebook with pen and paper, there are no tools to write math in text. No quick and dirty dragging in lines or graph axis. Though you grab a Ruler like this one and you are good for just about any strait line you could want...

If I was going to go back to college and do it all over again, I would get a Surface, or similar windows based tablet I can write on and use OneNote. The writing sucks compared to the SuperNote, but the flags and colors and other OneNote features are worth the trade.
