If you recall Steve Jobs was actually wearing and using the iPod when he announced it.

This AR device is so shoddy and weird looking I'm certain Jobs would have binned the whole project the first time he saw it in prototype.

kind of... he had it in his pocket: https://www.youtube.com/watch?v=kN0SVBCJqLs

but Steve is a showman and Tim is coordinator.

Yes, he was showing people the iPod was a normal thing a normal person would wear and use and still seem... normal.
