I would love to see the ability to have Apple TV be used on a Mac. I don't want to have to buy a TV just to use the Apple TV. I do like the UI and the App, but I would like to use my Mac as display.
I would like to hit a command and see the Apple TV take over the Mac and use the Apple TV like I normally do.
I know I'm probably the only guy that has this issue, I'm just minimalistic and have use my Mac as my sole display monitor, like with my PS4 now being able to be displayed on my Mac
