I'd like to thank everyone in this thread for helping me chose this TV.
Picked mine up at Costco today. I must say this is a very impressive TV for the money. I was very skeptical about trying this TV, but I'm glad I did.
I'm coming from two Panasonic plasmas. A ST30 and a UT50 that serve other areas of my home and I absolutely LOVE them. I had plans for an 65ST/GT50 for my family room. But there is just to much light during the day, plus video gaming.... SO glare and IR plus price made the Panasonic a poor choice.
I have been eyeing this at Costco every few weeks and the display unit is utter crap. I basically walked away with no interested and started looking into the Sharps. But in researching the Sharps this set kept coming up so I figured what the heck.... Glad I did.
I was able to fit the box into an 08 Santa fe with little drama (other than laying it down) but the trip was short and no curb jumping was done.
The stand sucks. Poor design by Vizio. A single neck on a TV this size seems like a bad idea. There should at least be two necks or more of a sleeve design. Wonder how many people cross thread the stand? Having to hold or prop an 80lb TV up a few inches while trying to align 3 screws coated in lock-tight into bare aluminium is tricky at best. I had hoped to avoid wall mounting it, but I looks like I'll be researching that. Can't let the kids/dogs near it as is.
There is a strong electronics/varnish smell coming off the unit. You can smell it from across my 30' family room. Hope that goes away in a few days.
The default "standard" mode was ok. Loaded the CNET custom movie settings and its much better. Plan to grab a Disney WOW and play around more, but the CNET settings are more than passable for now. I lucked out with 2 stuck pixels and 1 dead. The dead pixel is in the bottom 1/2 inch of the display but the stuck pixels are mid point. Hopefully WOW can cycle them. Most important however is no back-light/edge bleeding. The black screen (which is a bit more like gray coming from a Viera) is very uniform. I don't appear to have any banding. There is maybe a little unevenness/feathering in the very corners but it is tough to see at all on just some solid color slides. Again WOW might point this out and/or help me adjust it.
Off angle viewing is much better in a "normal" room than it was at Costco. Again it is not as good as my plasma... at 70" this TV is pretty hard to be at an 'off angle' without leaving the room.

What purpose does motion smoothing serve? Other than nausea and immediate motion sickness? Do people actual LIKE this setting? Maybe this is why I think the display at Costco looks like crap and it would explain why they have close to 20 of the things stacked there. I suppose its for video gaming or some such?
Didn't play much with the aps. Logged into netflix and it appears to work well. I have 5 WD SMP so I don't care about the 'smart' functions but its nice to know they are there. Any of them a most have/see? Amazon is nice because WD can't seem to get it added to their players.
