I’m using only this Rii i4 now. I don’t use the AirMote anymore. Navigation can be accomplished via the arrow keys, trackpad and scroll wheel.
The two buttons on the AirMote - Power and Auto Focus - are not found on the Rii i4.
For power ON, I press the button on the PPMax itself because it is on the coffee table next to me. But I can see how this can be a problem for those who mount it on the ceiling. For power OFF, I go to settings > Power > Shutdown.
As for Auto Focus, I’m not very worried now because my projector is pretty much at the same location. But @Philips_Support_P did mentioned that a future update will have the Auto Focus function available via the main screen. So that will resolve the need to rely on the AirMote in the future.
