I kept trying to like the "natural" direction setting for the scrolling behavior in the User Preferences settings for the trackpad, but I gave up. It just seemed.. UN-natural. Unlike on an iPhone or iPad, I didn't feel like I was gripping the MBA screen like a physical document to like the direction of the "natural" setting. I felt disconnected enough from the screen using a trackpad that the more default direction of scrolling from the previous OS Snow Leopard, Leopard, etc (ie turning "natural direction" off) felt more intuitive. Which setting in Lion do you guys prefer for your MBAs?
