Airplay has been a feature on the Apple TV for about 4 years now, and it has seemed to improve very little, if at all. Now some of it is developer fault, sure. But i would still put much of the blame on apple. Many video apps simply do not support airplay, Many video apps require you to stay in the app with the screen on. All apps (except youtube) will not let you continue to browse the app and you will be stuck in that one play mode. also I often run into a crappy experience where the app supports airplay but it simply won't work or it takes 10 seconds to load.
