Also, when typing in English, quicker access to the ' key would be nice.
Swipe up then instead of tap-and-hold, it should be much faster.
As for this whole "iPad for note taking" thing, I'm definitely old-school about using pen and paper. Something about the mechanics of writing down the words (and figures and equations) helps me to retain the information I'm learning. I don't know if typing would do the same because I wouldn't have the ability to doodle or highlight or draw little figures in quite the same way.
Of course, the generation that is in college right now has lived in front of a computer keyboard for their entire lives, so it's quite possible that you guys are far better at typing than you are at handwriting. When I was in grade school, it was all pencil and paper, and "computer class" was an hour a week in the library on a lab full of Apple ]['s. I didn't learn to touch type until the Typing class in grade 9 -- and that was on electric typewriters! By then it was too late - I have learned my own peculiar typing style which I can do far faster than traditional touch typing. Old habits die hard...
(Wow, that makes me feel old!)
So, sure, if a note-taking app on an iPad (or laptop) makes you feel productive, then hey, go for it. I just don't think I'd make that same choice for myself. (I do, however, remember how heavy my backpack used to get, with multiple subject binders and textbooks...)
And hey, some people will think you're a snob no matter what you're doing with the iPad. Someone on this very forum called me a douche simply for saying that (a) I liked my iPad better than my netbook and (b) Google Earth was more fun to use on the touchscreen.
