These "smart" TVs are still dumb devices in their childhood as it regards IP-based smartness. You mustn't buy them. You'd better buy a larger simple TV set for the same price, and keep browsing the net with your PV, notebook, tablet or mobile.
Keep listening to the news, then you may come back to this issue after 5 years, when you'll want to buy a new TV. I hope that in 5 years our Nobel-prized developers will manage to solve these IMHO simple technical problems.
