Well the idea is that its a handheld device
I think the Toshiba TVs are meant for living room displays, not portable ones. Never heard of someone with a 40 or 50 inch TV on the train.
This is what I was referring to - for these, you will probably have a number (maybe 3 or 5) of positions where you can get acceptable 3d viewing. I don't see wide adoption of these though and am yet to be convinced that this will be viable any time soon. Fingers crossed I'm wrong and we have full holographic displays being produced before the end of the year though.
