I was really looking forward to the AirPlay mirroring function, especially for games. So far, though, I've been underwhelmed. It seems buggy to me, with both sound and video stuttering. Real Racing 2 is unusable because half the time there's no video. Anyone else seeing this? Otherwise, both the AppleTV and the iPhone 4S are working phenomenally. Just not very well together, which bums me out a bit.
