1) Can you prompt us what the best TV series we can to buy in USA and Europe at this time?
2) What about Intel 3100 processor, does all new TV included it?
1.) I would recommend buying one from each manufacturer if funds permit. The base models are for all intents and purposes the same TV as the high end LED TVs, so there isn't much benefit from buying different models. If funds are limited, I would recommend buying a Samsung 650 and a Vizio (not sure model #s yet) when it's available later this month.
2.) No TVs use it. The first devices will be set top boxes (dvd players, blueray players, etc).
