I get that but I don't see the big issue whilst there is hardly any content.. Especially how people moan on these forums about it.. if there is hardly any content whats the point. But you could also argue if they making 5k iMacs they could of done 4k Apple TV.
I'm personally not that bothered purely because of the lack content.. They never perfected HD most channels still only have standard def programming..
Thats my main gripe.. get 1080p more widespread!
These are streaming devices though, not cable TV. I cannot remember the last thing I streamed from a box not in at least 1080P
