Set-top box is so 2010. In 2015 you can buy Smart TV that comes with apps and you need zero cables. If you want to play then connect PS4.
Apple is getting really tired when they release stuff like this. They used to innovators now they re-release old technology. I had first set-top box in 1982.
Smart TV is laggy. its apps have terrible UI, and many of them are not even working. its ecosystem has weak developer support.
and you need to upgrade a new TV if you want better "Smart" tv. just give me a TV that functions like monitor, like PC monitor.
