Kinect, to me, is nothing more than a glorified webcam.
I actually, truth be told, haven't seen any advertisements for the Kinect other than the occasional commercial. But advertising is just what people do. Advertising is just a part of our society. But yeah, i haven't used the Kinect, and I honestly don't want to. I mean, it's just a webcam designed for games. Their idea isn't really original, it's just a next-gen version of motion controls mixed with a webcam. But, the Kinect, I think, is just Microsoft's way of getting more casual gamers to play their games. Nintendo has learned to expand their horizons so that hardcore and casual gamers alike can play a game and enjoy it. Microsoft on the other hand needs to learn from Nintendo and reach out to hardcore players. I think the Kinect could be and will be a great thing in the future, but at the moment it's falling flat with what its got. The library is bad and it needs to reach out to a more hardcore audience.
Overall, Kinect just needs time. I'm sure it will be great eventually.
