You guys gotta try this out for yourselves. I've noticed that two-finger scrolling on the left half of the touchpad is more responsive than on the right half. Now maybe it's just my unit, so I'd appreciate some feedback. Here is how I scroll: I use my middle and ring fingers on my right hand. When they slide down, they're virtually horizontal to each other where they make contact with the touchpad. Another observation is that scrolling with my index and middle fingers with one above another (vertically aligned) seemed a bit more responsive than middle and ring fingers side-by-side (horizontally aligned). It's definitely not natural for my to scroll on the left half since I've right-handed. I hope there's a fix for this (or that it's just a problem with my unit). Try it out and let me know.
