Long time lurker...
Actually read all 29 pages... whew. Wanted to pipe in about a few things.
I'm a former multimedia engineer, so I'm not unfamiliar with some of these technologies... some I find interesting, some I'm not so keen on.
3D... Well, I suffer from daily migraines and vertigo, so 3D isn't high on my list. I haven't seen Avatar (I guess I'm the only one), yet, but I plan to maybe even this weekend more to give 3D a try than anything else. I'm hoping that the 3D is as well implemented as folks are saying.
I am encouraged about the 3D implementation on the Vizio for this reason. The less the brain has to reconcile, the fewer people won't be able to utilize the technology. I know that the cheaper 3D out there with the throw away glasses DOES make me sick, so the Active polarization is a BIG bonus for me, I don't really care how much the glasses cost.
I can tell not everyone read all the posts about how Vizio is doing full 3DHD because there IS definitely a way to do it over 1.3 even though they likely will ship the set with 1.4. I think Vizio realizes that while the 1.4a HDMI spec was recently put out there, broadcast content providers (as a previous poster just alluded to) currently don't have the bandwidth to accommodate full 3DHD via side by side 1080p60.
As we all know, "it's an engineering problem". They'll work it out. I'm more concerned with does it even work in a well lit room? I think the Vizio set might because the XpanD glasses are almost like ski goggles in that they block a good bit of ambient cross light. Not all, but a fair bit. It will be very interesting to demo it in a showroom.
Viewing angle. I realize they aren't using the Advanced True Wide Polarizer on the 72" set. And some folks freaked out about that. Off angle viewing is important, no doubt. However, I would caution that this different glass they are using, apparently from LG, with Vizio's titled "Wide Color Viewing Angle" technology may actually be enough in combination with the new LED implementation to deliver 178 degrees of viewing. At the very least, along with the 3D claims, Vizio has really stuck its neck out there. I noticed in both interviews the camera was at LEAST 45 degrees off axis and near 60 degrees on the gamertv interview in parts and I never saw that "privacy dimming" that happens with some LCDs and especially happens with filming LCDs (encoding off-angle LCDs in various pieces of footage used to just... well stink on ice).
After reading all the info on this TV, I told my wife that I FINALLY found a TV that would actually fill ALL my family's needs for our living room. I have a theater room (filled with boxes) that one day will house a projector and be a dedicated theater. But for the family in our VERY bright living room in Florida where we watch news, sports, and lots of movies, having a BIG tv that can handle it all and look decent in bright day and late at night at a reasonable price (service connected disabled vet with 4 kids... so my hobby is more of a looking hobby than a participating hobby...heh) is a Godsend.
We've made due with our 35" Hitachi Ultravision for the last 15 years. Just got FiOS and the picture is, frankly, still amazing. But I think the tube is about to go and nothing out there caught my eye that I could even approach affording. Until now.
Concerns? Lamp life for sure. I keep my TVs a long time. I'm 41 years old and only owned two TVs since I went out on my own at 18, a Mitsubishi 20" and the Hitachi. And I'm home alot, so I watch a fair amount. Not the 16hours a day bit... but a fair bit.
Support. I saw that Vizio has a fairly low failure rate, but I've also read some very disturbing posts from people in 2009 about how they were treated by Vizio support. What especially disturbed me was that if a new set was broken on delivery or just after, they only would send out refurbs. Yeah, I'm looking into that because that wouldn't cut it by me at all. That would be a deal breaker for me.
Other than that, I'm pretty geeked on the set. I was never looking for a Kuro, but something that could survive watching Discovery channel during the day in the bright Florida sun and look pretty good on movies, games and sports and do it at a price point that made sense.
I won't know until I've seen it with my eyes, but I'm hopeful.
Be well all.
P.S. Here is the Spec list from CES for the set. Someone posted the site, but this is the actual sheet.
