I have a 13" 2010 MBA, and just purchased a 2011 13" I7 MBA. Scrolling on the newer, faster MBA is incredibly choppy. I did a test today where I set my 2010 MBA next to the new one, and brought up several sites in Safari, Firefox, and Chrome. Every one on the 2010 scrolled smoothly. On the 2011, scrolling is choppy - instead of scrolling smoothly, it seems like it jumps in increments than makes it much harder to follow. Am I the only one seeing this?
