New MacBook Air announced on 'Back to the Mac' event.
The new MacBook Air includes a spacious Multi-Touch trackpad with a buttonless design, so you can click anywhere. The Multi-Touch trackpad also lets you pinch, swipe or rotate to adjust an image, zoom in on text or advance through a photo album. Try the four-finger swipe, swiping up or down to use Exposé and swiping left or right to switch among active applications. Or perform the new three-finger drag to move your windows from one place to another.
FaceTime Camera.
Hello, iPhone. (You too, iPod touch.)
Hidden inside the wafer-thin MacBook Air display is another engineering achievement — the FaceTime camera. It’s so thin (even thinner than the camera on iPhone 4) you barely notice it, but it’s incredibly capable. Using the new FaceTime for Mac application, currently in beta, you can make FaceTime calls over Wi-Fi with anyone who has a Mac, an iPhone 4 or the new iPod touch. And the video quality is so good, you can even chat in low-light conditions.
