I like that better. Muscle-memory, you know. I just caught myself  
unconsciously using two fingers to scroll on the XO - works fine ;)

I am using my MacBook's two-finger scroll in Sugar on VMWare, too.  
Having the same orientation would ensure the same behavior on non-XO  
hardware as on the XO.

When I first learned to fly by stick I was surprised that the machine  
goes up when you move the stick "down" (pull towards me). But after a  
while it feels natural.

I don't think there is an intrinsic advantage to one or the other. It  
would be different if it was actually grabbing the "page", but then  
the pointer should definitely move with the page.
