Myself and many of those reading this article already know a lot about technology. It was not difficult for us to tell that Microsoft's performance of Kinect wasn't done completely live, and we probably weren't that surprised either. After all, Microsoft did do the same thing when showing off "Project Natal" for the first time. Movements were often done on stage after they were already shown on screen. Plus in some of the few demos in which movements weren't early, they were so late that it either showcased terrible response lag or that again the demonstration was pre-recorded. To us, this seems like a huge hit for Microsoft. But think about how the general public, who has a completely different view will conceive Kinect.
