wow, you all must not have been to CES 2012 and seen the latest 3D TVs... very compelling way to enjoy certain kinds of content. Comparing HD and 3D is apples and oranges. 3D adds on top of HD.
Go see some good 3D movies at the theatre and you can also see good implementations of 3D content at your local Sony Store... they usually have some very nice NHK HD 3D b-roll on display with some of their TVs.
It takes time for people to adapt. This has happened every time when a paradigm shift occurred. When movie replaced theater, when sound and color were introduced into movie, and when computer animation was introduced, the content-providers did not how to utilize the new dimension at first, and eventually they got better and better. When Intel first came up with a 1000 transistor IC, people were asking why do we need a circuit with a thousand transistors, and look what we go now.
The question to ask for something like 3D is whether or not it adds value. If it does, then it becomes a question of what that value is worth. If Cost(3DTV) GT Worth(3DTV) then it is a bust. Otherwise, it is doable. Personally, the hassle of using glasses makes that cost too high. A good non-glasses implementation would be interesting, though. I'd seriously check it out.
P.S. I tried to use a 'greater-than' symbol above, but the comment police wouldn't let me. Sigh...
Will I be able to watch BSG on netflix in 3D? Probably not. With so much content in non-3D it would seem that 3D is a very small market. Now a 3D computer screen- that might be interesting. 3D charts, plots and diagrams. Now that I might use...
Personally, I am not that interested in 3DTV. I certainly would not pay a premium for it. I think a lot of the TV manufacturers believe that "smart" TV is more likely to drive upgrades than 3D alone. The newer smart TVs also include 3D capability, so even if that wasn't the reason for buying it, perhaps having the feature will make those of us who aren't interested in it come around. Yuzo Hirayama of Toshiba showed a slide that indicated that 68 percent of respondents to a survey said they weren't interested in 3DTV because of the glasses requirement.
Glassless 3DTV sounds appealing. There is no doubt better entertainment components delivered. Yet, I am still not convinced that 3DTV is providing more and better information than a regular HDTV. What do you think?
