Conclusion: The 50S2 is priced at an attractive $1169. The main two features of the G20 over the S1 is inbuilt Internet compatibility and the THX picture setting. The newer NEO PDP screen and other features are basically the same and so is the picture quality. Competition from other manufacturers in the plasma arena will be the Samsung PN50C6500 and Samsung PN50C7000 .
Summary: Panasonic Viera TC-P50S2 is not at all a bad choice. Its image quality falls very little behind of the one seen on models that cost much more, and it comes equipped with all that matters. Direct competition from other HDTV manufacturers, include models like Samsung PN50C6500 (which has better connectivity), or LG Infinia 50PK750 (which has streaming options, and THX certification to make it rise above), but, depending on your personal preferences, you can go for one...
