notes are not a good example since they use magnetic stylus or how's it called right. that means stylus not just press the screen, but connects to magnetic layer for all those fancy "tilt pen, press pen, hover pen" and so on. If we talk about touchscreen-only stylus, it works awful comparing to N900 resistive touchscreen stylus experience. and since I don't recall Chen promising any magnetic Note-like stylus support, the use of _any_ capacitive stylus would most likely suck just like any other capacitive device. the only good example I know is tablet Samsung Galaxy Active 8, where capacitive touch works with fingernail or thin metal objects. but still, it's way too far from perfect N900 resistive stylus use.
