I had the chance to try it today, my professor's friend/colleague/former student brought his in and let us try it in the Human Factors class (we also had a discussion about it).
Oh, one interesting discussion was social politeness with using electronic devices, he brought up that since the iPad (and other tablets) resemble a notebook (not laptop) more it may be perceived as more socially polite than using a laptop or a portable device for say taking notes or writing an email in a social setting such as a classroom.
So anyone else try the iPad and wanna share their thoughts?
