Who uses FaceTime on their phone regularly?
I never do, except for calling my parents overseas.
They don't want to see me they want to see their grand children.
Video calling has it's place but for 1 to 1 communication it's proven everyone (even the Sci-fi authors) wrong.
Watch the extensive use of video calling on Blade Runner as an example (set in 2019).
Comms in the 21st, listed by frequency of use, turned out to be:
1.Messaging
2.Voice
3.Video
So I'm arguing against myself here calling for FaceTime on the AppleTV?
No, not at all. Where video calls are very useful is in the many to many calls.
e.g. my family calling my parents.
Kids fight over the iPad/iPhone to get attention. Not good.
AirPlay sucks big time, it's seriously buggy and unreliable.
(I'm networking engineer by profession using Apples own Airport hardware - it 'aint the network to blame)
My TV hangs on the wall and with a camera on top of it would make the idea video conferencing setup.
I could refresh my TV and get one with Skype built in and a camera or I could wait and see if Apple come to their senses...
