Apple had a good show on stage, but I think the fake eyes is something you just can't optimize enough to make people like it.
No matter how you trying to make it look "natural", it just can't, there are countless edge cases out there, it will never be "natural looking". For example, what if it shows others that you're staring something straight ahead but when "in fact" you're looking at a giant window playing a movie? Isn't that a bit awkward?
Not to mention, the devices makes you constantly look like that you about to nick something. It's just look so funny.
