I've got a series 3 Samsung LCD TV. 1080p 40" from around 2006. It's shit by today's standards, yet no new TV is so amazingly better that I'd consider swapping it out, unless it conked out, or unless of course, I required a larger screen (which I don't in the forseeable future).
Rather, my next display techs will move into HMDs. I'm definetly liking the way the HMZ-T1 is panning out, but will keep out an eye for revisions and competitors.
Ideally; head tracking, 1080p, 3D of the quality that the HMZ-T1 is purportedly providing (i.e. best, bar none) and better/more comfortable ergonomics.
I'd go so far as to purchase multiples of such a headset for multiple people viewing at once.
