Hi, got my new MacBook Air 13" 2011 less than a week ago. It's great except one thing: the very bottom of the trackpad does not respond that well to my touch. If I place my finger so that it touches the edge of the trackpad and run the finger left-right back and forth, the cursor does not move at all or at best moves randomly. If I do the same on the left or right or top side of the trackpad, the cursor does move. This only affects the lowest 8-10 mm or so of the trackpad, but it's enough to allow me to keep my finger there comfortably. Very irritating. I'm not sure if this is expected behavior or not, so does your Air behave like this? I could call up Apple Store to get it replaced, but if I get another unit that behaves the same there is no point. It could be a design problem or it could be a problem with my particular unit. Thank you, looking forward to your answers.
