Well it's the first time you say Primesense instead of Kinect. I hope you understand that they are not exactly the same. The work MS had to do to make it work is what composes Kinect. It's precisely what Sony couldn't figure out, what they should be doing to use the technology with games.

The Sony tv is a neat idea. The problem is that people don't need this technology right now and more importantly people need to wear headphones... I've read that MS is also working on a tv that displays different images depending on where you're sitting but it was to make sure you get 3D without glasses and sit anywhere not necessarily in perfect front of the tv... both companies work hard, no need to think that unless they put a ton of marketing behind their product nobody would want them and/or the rival product is not working properly.

Kinect is impressively unimpressive. They did something which should never have worked and made it work. However because it was never really meant to be the whole device could never live up to the potential of what it could be. Kinect is the square peg that was made to fit into the round hole and it took a lot of work to make it fit. Because they somehow made Kinect fit they could also justify making a hole for Kinect in the next Xbox. Why else would they have a rumoured 8GB of RAM in their next system?

To sum up? Kinect is great and sucks at the same time. You're right if you say both or either.

I would say wii mote was best, it had plenty of games to prove it, its what helped the wii sell 90+ million. But yes they are different in alot of ways.

I really don't know either. I am no expert to tell and solve this error of Microsoft kinect. I hope you can conatct them through mail or even phone them about this matter. Microsoft's Kinect was supposed to be the next popular trend when it comes to input devices for your computer. But as it turns out, a 3-D motion controller known as the Leap Motion may be even more exciting. But I think it doesnt turn out that way. I read it here: Microsoft Xbox Kinect

Microsoft's Kinect was intended to be the next big thing on the subject of input devices for your computer. But as it turns out, a 3-D motion controller called the Leap Motion may be even more exciting. The fully 3-D motion control
program will be bundled with Asus PC laptops soon, then other platforms.

I'm pretty sure they made Kinect to make money and it did indeed make them an absolute shit ton of money so to label it a failure seems a bit silly to me.
