A crown the size of the pinhead isn't going to be much use to me: I've got fingers like sausages.
A lot of people think it it, but you don't grab the crown and twist it like a knob. Instead it is fluid enough to simply push up with the tip of your finger. It makes it a lot easier to use.
I think that's what has a lot of people confused with the orientation and backwards scrolling talk. It's just like touching to scroll, you grab a point on the screen and shift the content by that point; only instead of you dictating the location of the press, it's centered on the screen (or selected object). You will "push up" to shift the content down, but on the side, off the UI, and on the crown.
