eh, this is essentially a phone or a watch without a screen, and a bunch of "inventions" to accomodate the fact that it doesn't have a screen.

Ha you're kidding right? This is almost an attempt at adding another product to Apple's existing range of hardware, which is all phenomenally close to this hardware by being a chip, a camera, audio IO, and in their case a screen rather than a projector. You couldn't get closer if you tried.
