One bit of advice I would give to anyone thinking of buying a Smart TV and using it connected to the internet, check first its specification and minimum requirements. I bought a Samsung Smart TV with the intention of using it as an extra computer. However, on unpacking and setting up the TV, there was a warning saying that it can only be used with broadband speed in excess of 10mbs,, I only have 5, so was quite disappointed. Even with an ethernet cable the TV wouldn't play ball.
We bought the TV from John Lewis and explained to the assistant that one of the reason for buying this set, was to use it as a computer, it even came with a wifi keyboard. Either he didn't know this, or couldn't be bothered to tell us. This might not apply to all manufacturers, but it does with Samsung.
Having said that, it is a fantastic TV and stood out streets ahead of the competition when viewed from a distance in the showroom.
