This was one of the features that I was waiting most for - Airplay mirroring with iPad 2, using Apple TV. I wanted to use this feature for playing games on the TV, as well as FaceTime.
Here are the results so far:
Fifa 12 - wouldn't work at all - got stuck at the game loading screen.
Zombie Highway and Asphalt 6 - working, but with a lag. In Asphalt 6 I kept crashing, and ZH wasn't that good either.
FaceTime was OK, with a slight lag also.
I guess it would work nice for presentations and such, but for video games, it appears to slow.
What do you think?
