I tried kinect at a best buy today. It was super awful. The calibration was a pain, especially when you have to do it for each new person if you want it to read your movements at all. Even when it does that its slow, unresponsive and ultimately limited. I was playing kinect bowling and table tennis, and its nothing like the Wii Sports Resort versions i.e. tactile and/or fun. Navigating menus is a huge pain as well, there's a huge disconnect between your hand and the cursor, and often it struggles to catch up. Maybe in a controlled home environment these problems could be lessened, but it was a terrible impression. Before my concern was mainly with the space requirements, but I can't see this thing sustaining itself past this holiday season unless the mass market standards are far lower than I anticipated.
