The Novint XIO looks very interesting indeed. I have the Novint Falcon and I can say its a top quality product. If the XIO has the same build quality as the the Falcon that certainly won’t be an issue.
I’ve done some Half-Life2, Team-fortress and Dead-Space 2 on the Falcon and the drivers are 99%. Dead Space 2 is already scarey enough, but add that gun recoil and geez it has you sweating. Will definately be keeping an eye on this product.
Definately keen on seeing the reviews on this product once its out!
My main concern would be the readability of small text, seems the be the weak point of lower res VR solutions until now.
