"The device is tighter and more physically beautiful than the iPod Touch and it's got a better UI, the main menu's scrolling so natural through the swipe gestures. There's a little note on the side, under the volume toggle"Hello from Seattle." The power button is up top. The home button is nice and prominent, a bar rather than a round button on the Touch. It's smaller. And the accelerometer is more swift in responding to repositioning; images rotate very fast."
Take a look at the hands on video demo below...
