hi, i was watching the new video that apple posted on youtube called "Apple - OS X Mountain Lion" and at 2:44 there is a girl using a MacBook Air while the narrator is talking about the new notification center. what surprised me is that when the narrator says that to view the notification center you have to swipe to the left, the girl actually touch with two fingers the aluminum part next to the multitouch trackpad and the screen actually respond before even touching the multitouch trackpad. If the screen didn't respond i would have said that her fingers were hovering over the aluminum and then she touched the trackpad, but it seems she already touched the aluminum part. Am I hallucinating or apple missed something to announce at the WWDC. Here are the attached pictures of the parts that i'm talking about in three instances of the video. The first picture shows the normal screen, you can look at the right edge of the screen where the notification center should appear and there's nothing. The second picture shows the girl touching the aluminum body and the screen actually moved a little bit and you can see very close that the notifications are appearing while her fingers didn't touch yet the glass. the third picture shows that the notification center is showing and the glass isn't touched yet. p.S: watch the video if the pictures aren't clear.
