Using FaceTime, especially with young kids, is not a good experience. I'm not talking specifically about FaceTime, but
any video conferencing. The camera is not wide enough, so someone's gotta play cameraperson the whole time, or
you prop up the phone at a longer distance. But that is usually not practical, and even if you're sitting
down at a table or something, the screen is not big enough, nor the audio good enough, that keeps the kids engaged. Even with an iPad.
Maybe in the future, we have personal drones that are smart enough to play the camera part.
