The pointer is never as precise as I want it to be- mine is always a few pixels off, and every other tablet I've tried has been worse. You can argue or justify etc all you like, but I have always found this very disorienting.

Handwriting recognition is also approaching perfection, but it's not quite close enough yet. Maybe for some people with good handwriting it is 'there', but I'm not one of them, and I have to stop and correct a word too often. Plus, symbols recognition is tricky, along with words not out of the dictionary, so command prompt and programming are not fun.

Yes, stylus + touch screen > touch screen, imho. However, correct me if I am wrong, but Mr. Jobs did not show a stylus once during the presentation.
