If Sammy is any indication, you are going to be paying top dollars for smart features on a TV today 2012. Most people here would tell you buy a TV for its PQ, then purchase separate box(es) to augment your other needs, but if u insist everything inside TV, OK, your money.
Am one of those people who question WHY BROWSE ON A TV? Sure looks cool for your newbies, has that BECAUSE I CAN DO IT quality, but really a wireless keyboard is mandatory IMO, otherwise u gonna control the thing via a 10-buttons keypad? U must posses a high-pain threshold. Keep your browsing activity with your laptop as God intended, until they have FLASH on TV, then MAYBE.
A month ago I was browsing through Amazon on the Sammy E5000 series and lots of people then complained about this unit freezing up on the Smart features. They will get it ironed out *eventually* am sure, but do I wanna be the guinea pig for the vendor? Your call.
