TidBITS has some great insight into the iPad up, including a few little UI touches that we haven’t seen before.
They also had this to say about handwriting:
At no point did we wish we could write on the iPad with a stylus and have it recognize our handwriting. Although handwriting recognition has improved significantly since the days of the original Newton, it’s just not a good computing input mechanism. Just because you’re holding something that roughly resembles the shape of a notepad doesn’t mean it needs to be treated like one.
Handwriting, though, would be useful for a number of people — anyone who’s moving around and needs to take down quick notes while they’re standing and holding the device in one hand. Typing with the keyboard just doesn’t work very well in these cases.
