Having seen most of those proposed in one form or another in the past my response is about the same.

Can't see any of them being worth putting a headset on.

Can't see any of them being worth launching an app on a phone to stare through a camera at.

Some of them need some pretty next level ai.

The heads-up display on a car windshield seems pretty useful.

The rest are pretty underwhelming. Lots of things that make great demos, but not many that feel like I would come back to them.
