The guy broke NDA. If it had just be Woz he had shown it to then he might have gotten away with it. Unfortunately for him, there was YouTube video of him showing the device to all sorts of people besides Woz.
Also, he didn't just break the rules 10 minutes early. It was a 3G model and he broke NDA over a month early.
Correct, but according to the video he wasn't supposed to let anyone see his iPad prior to the launch of the Wifi model. In this case I can only go by the video, he may have shown it a month early or he may have only shown it 10 minutes early.
