Did you guys seen what the people already did with the hacked Kinect all around the net? Please, have a look in
here. Think what it will be done once the developer SDK will be let out of the door by M$.
Just have a look at the latest demo, the KinVi: A Kinect-Enabled Virtual Interface for Windows 7 Control.
I do not hate NP. But I have no respect for a firm which ask much more money for a product than it should, only because they have a monopolistic position. Which means the first occasion will arise to dump NP and go for another product, I will grab it without looking back or ever caring about NP.
Kinect has 3 cameras in it, and a LOT more plastic and internal hardware components than NP. If it also has some processors to do all the movement recognition internally, then even so much more, than NP's TrackIR. Yet, they have roughly the same price. Do you want to pick up a bet with me, regarding how much the cost for a NP TrackIR device will be lowered, once M$'s Kinect will put out the drivers for PC? Only then, you will actually see the true price of that product, but unfortunately, it will be too late. Even if NP will be forced to do it to survive competition, I won't but anything from them as soon as another (and better as it already is) product is out, even if much more expensive. I have money and I want to pay, I just don't want to be taken as a fool or enforced. All I just want is to be asked for a fair price.
Make no mistake, Kinect is the way user-computer interaction and control will be in the future. TrackIR, mouse's and keyboards have to go to computer history's recycle bin, and will do it, sooner than you'd think.
