I recently purchased the Sony Bravia EX720 from a local electronics store (and not Amazon, since I prefer to make large electronic purchases locally in the event I need to quickly return and exchange a defective item). Overall, the TV is good, but not great. Here is a quick down and dirty list of "in my opinion (IMO)" pros and cons:

Pros:

- High quality LED side-lit LCD screen
- True 1080P 3D and Hi-definition capable, but with some limitations
- Colors and contrast are vibrant, once you take the time to manually adjust the picture settings
- Built-in 3D transmitter; no need to buy the external transmitter which saves you about $35
- 3D effects are very good overall, but best results can only be attained by watching 3D Blu Ray movies
- Artifical 3D option in the 3D options works decently and provides an alternative to playing PC games in 3D without having to use the NVidia 3D Vision or 3DTV Play drivers; this allows you to maintain up... Read more

Sony offers a variety (i.e. confusing array) of very similar TV models. I wanted a 60" screen, but decided on the EX rather than the NX once I understood the differences. In case anyone else finds themselves similarly confused, here is my take on the two models.

The NX costs $400-500 more than the EX, but seems to have the same basic TV inside. For me, the following features weren't worth the extra several hundred bucks:

(1) WiFi -- Wireless access is noticeably slower than wired for streaming video, so I wouldn't use that if I had it.

(2) Gorilla Glass -- The NX weighs about six pounds more, mainly because of the giant sheet of "Gorilla Glass" covering the front screen. Sony calls this feature a border-less "monolithic design", but I found it a bit silly. The TV looks border-less only when it's turned off. The NX actually has a slightly larger border than the cheaper EX model. But perhaps Sony expects their customers to not turn their sets on,... Read more

*UPDATE* May 19, 2011
I've had this TV for over a month now, and just wanted to provide an update:

Picture: CUSTOM SETTINGS! Out-of-the-box, the picture isn't the best quality. There is some graininess, a noticeable soap opera effect and some blockiness with moving pictures. EVERY owner should calibrate the settings to their liking. Also, it's very important to turn off the ECO sensor -- your TV will be much, much brighter. I followed the custom settings on flatpanelshd.com, where the reviewer tweaked the settings for best picture output, down to advanced settings like B-Gain and R-Gain. From there I messed around with the other settings until I found a picture I'm very happy with.

Comparison: Two of my friends bought a 55-inch LG LW5600 and I've spent a good time watching their TVs. The LG uses passive 3D so the glasses are super cheap and comfortable -- I hate to say it, but the 3D on that TV probably looks better overall. They also brag about an 8 million... Read more
