I've been looking at the apple tv for about a week now. Looked at reviews, looked at prices, looked at what is can do. But every time I see a review they just say "it's good" then go on describing really what I can find out on the web site. But I keep hearing about lack 4k, what worries me. I'm not to sure what 4k is and the only thing I can really compare it to is blue-ray. So as long as it has a blue-ray quality video I'm happy. So would you say the apple tv what I'm looking? A high quality video.
