There is a general lack of android tv reviews and websites with articles about android tv so it's hard to learn about it really.
I currently have a samsung smart tv and I think it's good I mostly use it for gaming and playing content from my external hard drive.
I have seen that the Sony bravias themselves are good tvs. But is it worth paying a few hundred extra for android tv?
I am most keen on the fact that with it being android it will keep more up to date than other smart tv operating systems and that will in turn make it worth the investment.
Buy a good, cheap, dumb TV. Use the extra money & get a Shield TV PRO.
