Pros: Reasonable price
Good picture quality
Viera connect with Viera market to download apps
Easy setup interface
The television itself is attractive

Cons: Very loud buzzing sound when the screen is predominately white. I've looked around in the options and so far have found nothing that resolves it. There is a "Mosquito N.R." option that sounds like it addresses this issue, but toggling it on and off does nothing. This is an extremely annoying issue that I don't have with the '42 Panasonic Plasma of the previous year's series.
Movement is either unnaturally fluid or noticeably jittery. Depending on the motion settings you have it on, fast movements on the television either show up in a surreal fluid motion that looks like it was captured on a home video recorder or the picture gets choppy every time that the rapid action occurs on-screen.

Other Thoughts: I'm not an expert on TVs by any means and have only taken a cursory glance around the internet searching for a clue. There isn't a whole lot of info about this particular model since it is relatively new. I'd love to find some quick, easy answers on how to resolve the issues I have with the TV, but the last time I called Panasonic support for an issue I ended up going around in circles for hours with their tech support.
Overall, the TV is okay. Given another chance to choose a TV, I'm not sure that I'd buy this one again.
