I'm a big fan of Panasonic Plasma's - currently have 3 of them.
Owned a LCD for a few years and didn't care for it that much, but suffered thru it because of the size (65" deal off woot.com). Last year, we rearranged the main living area, and moved the TV to a built in cabinet, so had to downsize from 65" to a 50", tried out a Samsung LCD and didn't care for it, took it back to Costco and ordered a Panasonic Plasma 3D model (don't own any 3D glasses though).
2 of our 3 Panasonic's have wifi in them (the new one is built in, the other one is with a USB network adapter). We don't really use the features that often, but there are times when we watch something on Amazon Prime TV.
Mostly stream movies from an iTunes device, so don't use the wifi option on the TV that often, I have Apple TV's on the TV's.
