The HMZ is a "portable" large screen TV, not a VR device. There is no headtracking, no positional tracking, no lenses to warp the image around your FOV. Even Sony knows this is not VR, that's why they're basically "cloning" the Rift for Project Morpheus, instead of further developing the (for VR purposes) inferior HMZ tech.
Better image quality for watching BlueRay on a virtual screen 15 feet in front of your face is NOT an important quality for VR. What is important is to get the tracking, latency, optics and FOV right. The screen quality on Oculus will get there. Since they've been partnering with Samsung we know they will get there. Its a matter of when, not if. And I am very much looking forward to see what Sony has up their sleeves too. They're certainly not sleeping in Japan, I'm sure they're working on an improved version of Morpheus as we speak.
Back to OP: I agree. Hope your PC gets back soon.
