Quick question - opinions on a device for playing youtube videos through a TV? A friend wants to be able to watch youtube videos on his (non-"smart") TV, figured I'd ask about what the best way to accomplish that is. I assume the roku will do this? How easy is it to navigate? He's not a techie... He tried a chromecast with his android tablet, but it didn't work well at all, as it seemed to have very poor wireless radio strength. Now he's primarily using an iPad with youtube.
