1. The "Model" you have.
Sony KDL-40XBR2
2. What convinced you to purchase this particular model.
Lived with a Maxent EDTV 42" plasma for over 2 years and was itching for a 1080p capable LCD/Plasma for video games. The massive amounts of inputs as well as the feature set for image processing is really great for anyone who has a wide variety of needs (DVR, X360, PS3, and the list foes on and on...).
After going to a local Sony Style store they had a $300 gift card for purchasing the XBR2, so I ended up getting a 5-year warranty for free.
3. What you like best about your LCD.
X360 is simply stunning (albeit in 1080i using Component...) and the abundance of source inputs allows tons of devices to be connected without having to resort to a HDMI switcher.
4. What you don't like about your LCD.
X360/VGA cable is worthless is it's current form since the 1080p signal just won't jive with the KDL-40XBR2. This really isn't a knock on the Sony, but since the only real 1080p content I have comes from the X360 it does not make for a stellar out-of-box experience after spending that much money.
5. What "Feature(s)" you wish your LCD had.
There's nothing with the image processing or image quality I'd change, but there are some physical things:
1.) I wish the source input connectors pointed down instead of outwards so that wall mounting the LCD would work better with low-profile mounts.
2.) A wider remote, it feels like your holding a broomstick to control an expensive TV
6. What advice or suggestion would you make to the "Manufacturer" about your LCD.
Make the marketing brochures more informative about the differences between models. It took 3 sales people to figure out that the only difference between the KDL-40XBR2 and KDL-XBR3 was a "polished piano black" bezel and $300...
7. What was your biggest "Surprise" after you received your LCD.
How well the out-of-box expereince was...

A few of the people that helped me move the TV home from the store were unimpressed with the picture quality at the store. After we moved the TV in from the car I held them captive until they saw X360 on the display, and there were no doubts that the picture quality was exceptional.
8. What "Problems or Issues" have you had with your LCD.
The X360/VGA issue is frustrating, you'd think that Microsoft would try out their new features on some of the best and hottest displays on the market. But whatever...
9. Do you really think that todays "Prices" are worth it.
This is not a cheap TV by any means, but you do get a lot of quality for the price. If you have good HD source this display really shines, but if you're mainly viewing SD source than the price can feel oversaturated.
10. Any additional information that you want to add is encouraged.
At the store I was flip-flopping between the KDL-40XBR2 and KDL-46XBR2 for quite a while. In the end I chose the KDL-40XBR2 and am SOOOOOO glad that I did! The main difference in image quality will likely come from the source content, not from 40" vs 46"

Granted coming from a Maxent EDTV plasma just about anything would be a giant upgrade, but the out-of-box experience for this display was truly exceptional.
