Keep in mind that now that you can use your Apple keyboard or any bluetooth keyboard to control your Apple TV that the keyboard can only be paired to only one device at a time.
Or way simpler, the remote.app on any other iDevice (not new). Yay!
Except the latest update hosed up the ability for the iPad remote.app to connect reliably to the ATV. It was flawless for me before the update. Frustrating. How does one report a bug for the ATV?
I have not experienced that personally, but there seems to be some issues.
