Just because something works, doesn't mean it isn't outdated.
I'd be surprised if Plasma is still around in five years time. I would be even more surprised if LCD is
not.

Are you sure about that these days?

It was extremely disheartening. I don't understand why so many people in the Sony threads keep insisting that off-axis viewing isn't a problem on these sets - it's actually very unacceptable.
We don't have those kind of stores here; what kind of lighting setup do they have? I can't imagine it being especially dim for safety reasons, and in a reasonably well lit environment, you should be able to move much further than 15° off-axis before you notice any kind of loss of contrast - at least not having the black level rising. Depending on the panel type, you might see colour or gamma shifting, or a loss of brightness though. As soon as there are any lights on in my room, any black level issues at an angle disappear until you are at such an angle you can't watch the picture anyway.
With the better IPS panels in a bright room, there's almost no change to the image as you move off to the side. (a different story in the dark though)
And Plasma black levels don't look "inky" in any environment to me; if you're in a dark environment, it's enough to let you see that they only have about 10,000:1 contrast, and if you're in a well lit environment, contrast of the panel is reduced even further.
Are you sure it was a HX950 and not an edge-lit set? (perhaps the HX850) Was local dimming actually enabled on the set? If we are actually talking about
black level, it remains black at any angle, because those areas of the screen are turned off. What happens when you go off-axis with an LED backlit screen is that you start seeing haloing around bright objects. Black areas stay black.
An example
I posted some time ago, one of the worst case scenarios for a local dimming set; bright white text (the colour is moire from the camera) on a full black background in a dark room, at a much steeper angle than you could actually watch the TV from.

Unfortunately Imageshack seems to have removed the full resolution images now, and I don't have a local copy. (they seem to have started doing that some time this year)
Admittedly the newer HX920 and HX950 use lower contrast panels than my HX900, but viewing angle was never UV2A's strong point.
You won't have any argument from me about viewing angle being less than ideal on any LCD - it's the main area they're lacking in - but it's never been
that bad. Depending on how close you are to the panel, 15° is most likely less than 2ft off centre.
Plasma is clearly better in that regard, but I don't buy high-end displays to be sitting anywhere except directly in front of them when watching anything, so it's almost irrelevant in my opinion.

Congratulations for not reading my post. Even if you keep them at a dim output level in a darkened room, the ABL automatically dims the picture on a Plasma display. Bright outdoor scenes are displayed dimmer than they are supposed to, even if you set peak brightness to
half the reference level for flat panel displays. With LCD, there are no brightness fluctuations depending on the picture content being displayed.

I wonder if anyone here knowledgeable about the cost of TV manufacture knows how feasible it would be to produce a double-layer panel now?
Surely the cost of LCD manufacture is dropping at a considerable rate, and it's becoming more realistic to have something like the old
Sharp 1,000,000:1 contrast prototype that used two LCD panels layered on top of each other.
With IGZO allowing the panels to transmit much more light, and contrast in excess of 2,000:1 native (3,500:1+ for Sharp's UV2A) that could result in an edge-lit panel with 4,000,000:1 native contrast or greater, and I'm sure that uniformity correction could be implemented.
