You would be more impressed by a Wacom penabled tablet or phone, like the Galaxy Note.

My Wacom penabled tablet/laptop convertible PC was invaluable at taking calculus and economics notes in Word 2007 - You can type all the text, then pick up the stylus and draw formulas, graphs, and symbols where you want.

It was such a powerful use-case for me that I don't understand why nobody has copied it yet.

Off topic, but you could have done your notes in LaTeX as well. In fact, in my experience, using TeX for math formulas (I did a semester's worth of calculus notes in LaTeX) is actually faster than writing them out by hand (\unless I give up on trying to make the result readable at all, and maybe even then.

Admittedly, graphs and illustrations were an issue. In fact, I basically didn't bother with either. But just for text and math notation, LaTeX was awesome.

I took my math and CS notes in LaTeX because I hated writing and wanted everything together in files that I had source control on, but I definitely didn't find it faster to type in the equations than write them out by hand, even with a fair bit of practice at Emacs keyboard shortcuts for common stuff.

Are they lag free? The video I saw of the Galaxy Note's sketch/note app showed lag.
