I remember I saw, a few years ago, someone taking notes with a tablet computer (might have been the first generation iPad), and also using a stylus. What tools are best to be used for that matter (i.e. if you want your iPad to replace pen and paper, and in addition to taking written notes by means of its virtual keyboard, you also need some sort of a stylus to draw diagrams and other things that can't be done with a keyboard)? I thought the gadget's Notes app would also include drawing, but apparently that's not the case (did some search of "sketch" in the app store, but I'm still trying to figure out which one is the best). As for the stylus... did early versions of iPad include it? So far I only tried to use the stylus from my faithful Nokia phone, but nothing happened (probably too thin?).
