Echo has a built-in microphone and people have significant concerns on privacy.- it always listens just to see if theres any command- amazon claims that echo ignores all if theres no spesific command that triggers echo but lets face it. Feels awkward. And it always will feel awkward.

Now think about that. Apple may has advanced security systems. — this is controversial- but a camera that is connected to internet all the time. Not like your smartphone or laptop, this is a brand new area.

But at the end, this is progress. And as mentioned before, apple does it well.
